If it is possible regenerate the spine it would be possible avoid the complications of the surgery and achieve better results. Our study involves the use of mesenchymal stem cells in regenerating the discs. Our study involved 10 patients who presented with degenerative disc disease between 2008-2011 in our hospital. After adequate pre-operative check prepared mesenchymal stem cells were injected into the disc spaces. These patients were subjected to conservative therapy for a minimum of six weeks before they were accepted into the study. They were followed up regularly for a minimum of 2years with serial radiographs and MRI. 8 out of the 10 patients had completed reduction in the pain. The T2 weighted MRI images in 9 out of the 10 patients showed a bright signal compared the previous Images which indicated that there was improvement in the hydration levels. From the case study of 10 patients who were subjected to mesenchymal cell therapy in our hospital, we can conclude that the use of mesenchymal cells in treatment of intervertebral disc degeneration in a safe and effective option. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=mesenchymal%20stem%20cells" title="mesenchymal stem cells">mesenchymal stem cells</a>, <a href="https://publications.waset.org/abstracts/search?q=intervertebral%20disc" title=" intervertebral disc"> intervertebral disc</a>, <a href="https://publications.waset.org/abstracts/search?q=the%20spine" title=" the spine"> the spine</a>, <a href="https://publications.waset.org/abstracts/search?q=disc%20degeneration" title=" disc degeneration "> disc degeneration </a> </p> <a href="https://publications.waset.org/abstracts/16025/a-prospective-study-on-the-efficacy-of-mesenchymal-stem-cells-in-intervertebral-disc-regeneration" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/16025.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">371</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3718</span> Up-Regulation of SCUBE2 Expression in Co-Cultures of Human Mesenchymal Stem Cell and Breast Cancer Cells</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hirowati%20Ali">Hirowati Ali</a>, <a href="https://publications.waset.org/abstracts/search?q=Aisyah%20Ellyanti"> Aisyah Ellyanti</a>, <a href="https://publications.waset.org/abstracts/search?q=Dewi%20Rusnita"> Dewi Rusnita</a>, <a href="https://publications.waset.org/abstracts/search?q=Septelia%20Inawati%20Wanandi"> Septelia Inawati Wanandi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Stem cell has been known for its potency to be differentiated in many cells. Recently stem cell has been used for many treatment of degenerative medicine. It is still controversy whether stem cell can be used for therapy or these cells can activate cancer stem cell. SCUBE2 is a novel secreted and membrane-anchored protein which has been reported to its role in better prognosis and inhibition of cancer cell proliferation. Our study aims to observe whether stem cell can up-regulate SCUBE2 gene in MCF7 breast cancer cell line. We used in vitro study using MCF-7 cell treated with stem cell derived from placenta Wharton's jelly which has been known for its stemness and widely used. Our results showed that MCF-7 cell line grows up rapidly in 6-well culture dish. Stem cell was cultured in 6-well dish. After 50%-60% MCF-7 confluence, we co-cultured these cells with stem cells for 24 hours and 48 hours. We hypothesize SCUBE2 gene which is previously known for its higher expression in better prognosis of breast cancer, is up-regulated after stem cells addition in MCF7 culture dishes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=breast%20cancer%20cells" title="breast cancer cells">breast cancer cells</a>, <a href="https://publications.waset.org/abstracts/search?q=inhibition%20of%20cancer%20cells" title=" inhibition of cancer cells"> inhibition of cancer cells</a>, <a href="https://publications.waset.org/abstracts/search?q=mesenchymal%20stem%20cells" title=" mesenchymal stem cells"> mesenchymal stem cells</a>, <a href="https://publications.waset.org/abstracts/search?q=SCUBE2" title=" SCUBE2"> SCUBE2</a> </p> <a href="https://publications.waset.org/abstracts/84557/up-regulation-of-scube2-expression-in-co-cultures-of-human-mesenchymal-stem-cell-and-breast-cancer-cells" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/84557.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">340</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3717</span> Human Mesenchymal Stem Cells as a Potential Source for Cell Therapy in Liver Disorders</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Laila%20Montaser">Laila Montaser</a>, <a href="https://publications.waset.org/abstracts/search?q=Hala%20Gabr"> Hala Gabr</a>, <a href="https://publications.waset.org/abstracts/search?q=Maha%20El-Bassuony"> Maha El-Bassuony</a>, <a href="https://publications.waset.org/abstracts/search?q=Gehan%20Tawfeek"> Gehan Tawfeek</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Orthotropic liver transplantation (OLT) is the final procedure of both end stage and metabolic liver diseases. Hepatocyte transplantation is an alternative for OLT, but the sources of hepatocytes are limited. Bone marrow mesenchymal stem cells (BM-MSCs) can differentiate into hepatocyte-like cells and are a potential alternative source for hepatocytes. The MSCs from bone marrow are a promising target population as they are capable of differentiating along multiple lineages and, at least in vitro, have significant expansion capability. MSCs from bone marrow may have the potential to differentiate in vitro and in vivo into hepatocytes. Our study examined whether mesenchymal stem cells (MSCs), which are stem cells originated from human bone marrow, are able to differentiate into functional hepatocyte-like cells in vitro. Our aim was to investigate the differentiation potential of BM-MSCs into hepatocyte-like cells. Adult stem cell therapy could solve the problem of degenerative disorders, including liver disease. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bone%20marrow" title="bone marrow">bone marrow</a>, <a href="https://publications.waset.org/abstracts/search?q=differentiation" title=" differentiation"> differentiation</a>, <a href="https://publications.waset.org/abstracts/search?q=hepatocyte" title=" hepatocyte"> hepatocyte</a>, <a href="https://publications.waset.org/abstracts/search?q=stem%20cells" title=" stem cells "> stem cells </a> </p> <a href="https://publications.waset.org/abstracts/13255/human-mesenchymal-stem-cells-as-a-potential-source-for-cell-therapy-in-liver-disorders" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/13255.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">519</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3716</span> Umbilical Cord-Derived Cells in Corneal Epithelial Regeneration</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hasan%20Mahmud%20Reza">Hasan Mahmud Reza</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Extensive studies of the human umbilical cord, both basic and translational, over the last three decades have unveiled a plethora of information. The cord lining harbors at least two phenotypically different multipotent stem cells: mesenchymal stem cells (MSCs) and cord lining epithelial stem cells (CLECs). These cells exhibit a mixed genetic profiling of both embryonic and adult stem cells, hence display a broader stem features than cells from other sources. We have observed that umbilical cord-derived cells are immunologically privileged and non-tumorigenic by animal study. These cells are ethically acceptable, thus provides a significant advantage over other stem cells. The high proliferative capacity, viability, differentiation potential, and superior harvest of these cells have made them better candidates in comparison to contemporary adult stem cells. Following 30 replication cycles, these cells have been observed to retain their stemness, with their phenotype and karyotype intact. Transplantation of bioengineered CLEC sheets in limbal stem cell-deficient rabbit eyes resulted in regeneration of clear cornea with phenotypic expression of the normal cornea-specific epithelial cytokeratin markers. The striking features of low immunogenicity protecting self along with co-transplanted allografts from rejection largely define the transplantation potential of umbilical cord-derived stem cells. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cord%20lining%20epithelial%20stem%20cells" title="cord lining epithelial stem cells">cord lining epithelial stem cells</a>, <a href="https://publications.waset.org/abstracts/search?q=mesenchymal%20stem%20cell" title=" mesenchymal stem cell"> mesenchymal stem cell</a>, <a href="https://publications.waset.org/abstracts/search?q=regenerative%20medicine" title=" regenerative medicine"> regenerative medicine</a>, <a href="https://publications.waset.org/abstracts/search?q=umbilical%20cord" title=" umbilical cord"> umbilical cord</a> </p> <a href="https://publications.waset.org/abstracts/117218/umbilical-cord-derived-cells-in-corneal-epithelial-regeneration" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/117218.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">156</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3715</span> Differential Expression of Biomarkers in Cancer Stem Cells and Side Populations in Breast Cancer Cell Lines</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dipali%20Dhawan">Dipali Dhawan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Cancerous epithelial cells are confined to a primary site by the continued expression of adhesion molecules and the intact basal lamina. However, as the cancer progresses some cells are believed to undergo an epithelial-mesenchymal transition (EMT) event, leading to increased motility, invasion and, ultimately, metastasis of the cells from the primary tumour to secondary sites within the body. These disseminated cancer cells need the ability to self-renew, as stem cells do, in order to establish and maintain a heterogeneous metastatic tumour mass. Identification of the specific subpopulation of cancer stem cells amenable to the process of metastasis is highly desirable. In this study, we have isolated and characterized cancer stem cells from luminal and basal breast cancer cell lines (MDA-MB-231, MDA-MB-453, MDA-MB-468, MCF7 and T47D) on the basis of cell surface markers CD44 and CD24; as well as Side Populations (SP) using Hoechst 33342 dye efflux. The isolated populations were analysed for epithelial and mesenchymal markers like E-cadherin, N-cadherin, Sfrp1 and Vimentin by Western blotting and Immunocytochemistry. MDA-MB-231 cell lines contain a major population of CD44+CD24- cells whereas MCF7, T47D and MDA-MB-231 cell lines show a side population. We observed higher expression of N-cadherin in MCF-7 SP cells as compared to MCF-7NSP (Non-side population) cells suggesting that the SP cells are mesenchymal like cells and hence express increased N-cadherin with stem cell-like properties. There was an expression of Sfrp1 in the MCF7- NSP cells as compared to no expression in MCF7-SP cells, which suggests that the Wnt pathway is expressed in the MCF7-SP cells. The mesenchymal marker Vimentin was expressed only in MDA-MB-231 cells. Hence, understanding the breast cancer heterogeneity would enable a better understanding of the disease progression and therapeutic targeting. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cancer%20stem%20cells" title="cancer stem cells">cancer stem cells</a>, <a href="https://publications.waset.org/abstracts/search?q=epithelial%20to%20mesenchymal%20transition" title=" epithelial to mesenchymal transition"> epithelial to mesenchymal transition</a>, <a href="https://publications.waset.org/abstracts/search?q=biomarkers" title=" biomarkers"> biomarkers</a>, <a href="https://publications.waset.org/abstracts/search?q=breast%20cancer" title=" breast cancer"> breast cancer</a> </p> <a href="https://publications.waset.org/abstracts/21001/differential-expression-of-biomarkers-in-cancer-stem-cells-and-side-populations-in-breast-cancer-cell-lines" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/21001.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">526</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3714</span> Isolation, Characterization and Myogenic Differentiation of Synovial Mesenchymal Stem Cells</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fatma%20Y.%20Meligy">Fatma Y.

Then to assess the potentiality of myogenic differentiation of these isolated MSCs. Methods: The MSCs were isolated from synovial membrane by digestion method. Three adult rats were used. The 5 -azacytidine was added to the cultured cells for one day. The isolated cells and treated cells are assessed using immunoflouresence, flowcytometry, PCR and real time PCR. Results: The isolated stem cells showed morphological aspect of stem cells they showed strong positivity to CD44 and CD90 in immunoflouresence while in CD34 and CD45 showed negative reaction. The treated cells with 5-azacytidine was shown to have positive reaction for desmin. Flowcytometric analysis showed that synovial MSCs had strong positive percentage for CD44(%98)and CD90 (%97) and low percentage for CD34 & CD45 while the treated cells showed positive percentage for myogenic marker myogenin (85%). As regard the PCR and Real time PCR, the treated cells showed positive reaction to the desmin primer. Conclusion: The adult MSCs were isolated successfully from synovial membrane and characterized with stem cell markers. The isolated cells could be differentiated in vitro into myogenic cells. These differentiated cells could be used in auto-replacement of diseased or traumatized muscle cells as a regenerative therapy for muscle disorders and trauma. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=mesenchymal%20stem%20cells" title="mesenchymal stem cells">mesenchymal stem cells</a>, <a href="https://publications.waset.org/abstracts/search?q=synovial%20membrane" title=" synovial membrane"> synovial membrane</a>, <a href="https://publications.waset.org/abstracts/search?q=myogenic%20differentiation" title=" myogenic differentiation "> myogenic differentiation </a> </p> <a href="https://publications.waset.org/abstracts/29107/isolation-characterization-and-myogenic-differentiation-of-synovial-mesenchymal-stem-cells" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/29107.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">306</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3713</span> BSYJ Promoting Homing and Differentiation of Mesenchymal Stem Cells at the Retina of Age-Related Macular Degeneration Model Mice Induced by Sodium Iodate</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lina%20Liang">Lina Liang</a>, <a href="https://publications.waset.org/abstracts/search?q=Kai%20Xu"> Kai Xu</a>, <a href="https://publications.waset.org/abstracts/search?q=Jing%20Zhang"> Jing Zhang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Purpose: Age-related macular degeneration (AMD) is a major leading cause of visual impairment and blindness with no cure currently established. Cell replacement is discussed as a potential therapy for AMD. Besides intravitreal injection and subretinal injection, intravenous administration has been explored as an alternative route. This study is to observe the effect of BSYJ, a traditional Chinese medicine on the homing and differentiation of mesenchymal stem cells transplanted via tail vein injection in an age-related macular degeneration mouse model. Methods: Four-week-old C57BL/6J mice were injected with 40 mg/kg NaIO₃ to induce age-related macular degeneration model. At the second day after NaIO₃ injection, 1×10⁷ GFP labeled bone marrow-derived mesenchymal stem cells (GFP-MSCs) were transplanted via tali vein injection into the experimental mice. Then the mice were randomly divided into two groups, gavaged with either BSYJ solution (BSYJ group, n=12) or distilled water (DW group, n=12). 12 age-matched healthy C57BL/6J mice were fed regularly as normal control. At day 7, day 14, and day 28 after treatment, retina flat mounting was used to detect the homing of mesenchymal stem cells at the retina. Double-labeling immunofluorescence was used to determine the differentiation of mesenchymal stem cells. Results: At 7, 14, 28 days after treatment, the numbers of GFP-MSCs detected by retina flatmount were 10.2 ± 2.5, 14.5 ± 3.4 and 18.7 ± 5.8, respectively in the distilled water group, while 15.7 ± 3.8, 32.3 ± 3.5 and 77.3 ± 6.4 in BSYJ group, the differences between the two groups were significant (p < 0.05). At 28 days after treatment, it was shown by double staining immunofluorescence that there were more GFP positive cells in the retina of BSYJ group than that of the DW group, but none of the cells expressed RPE specific genes such as RPE65 and CRALBP, or photoreceptor genes such as recoverin and rhodopsin either in BSYJ group or DW group. However, GFAP positive cells were found among the cells labeled with GFP, and the double labeling cells were much more in the BSYJ group than the distilled water group. Conclusion: BSYJ could promote homing of mesenchymal stem cells at the retina of age-related macular degeneration model mice induced by NaIO₃, and the differentiation towards to glial cells.

This stem cell source represents an advantage over the use of bone marrow or mobilized peripheral blood because it has a lower incidence rate of graft-versus-host disease, probably due to fewer immunological compatibility restrictions. However, its low cellular dose limits its use in pediatric patients. This work proposes the standardization of a cell expansion technique to compensate for the dose of infused cells through the ex-vivo manipulation of hematopoietic progenitor cells from umbilical cord blood before transplantation. The expansion model is carried out through co-cultures with mesenchymal stem cells (MSC) from bone marrow (BM) and less explored fetal tissues such as Wharton's jelly (WJ) and umbilical cord blood (UCB). Initially, a master cell bank of primary mesenchymal stem cells isolated from different sources was established and characterized following International Society of Cell Therapies (ISCT) indications. Additionally, we assessed the effect of a short 25 Gy cycle of gamma irradiation on cell cycle arrest of mesenchymal cells over the support capacity for the expansion of hematopoietic stem cells from umbilical cord blood was evaluated. The results show that co-cultures with MSC from WJ and UCB allow the cellular dose of HSPC to be maximized between 5 and 16 times having a similar support capacity as BM. In addition, was evaluated the hematopoietic stem progenitor cell's HSPC functionality through the evaluation of migration capacity, their differentiation capacity during culture time by flow cytometry to evaluate the expression of membrane markers associated with lineage-committed progenitors, their clonogenic potential, and the evaluation of secretome profile in the expansion process was evaluated. So far, the treatment with gamma irradiation maintains the hematopoietic support capacity of mesenchymal stem cells from the three sources studied compared to treatments without irradiation, favoring the use of fetal tissues that are generally waste to obtain mesenchymal cell lines for ex-vivo expansion systems. With the results obtained, a standardized protocol that will contribute to the development of ex-vivo expansion with MSC on a larger scale will be achieved, enabling its clinical use and expanding its application in adults. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ex-vivo%20expansion" title="ex-vivo expansion">ex-vivo expansion</a>, <a href="https://publications.waset.org/abstracts/search?q=hematopoietic%20stem%20cells" title=" hematopoietic stem cells"> hematopoietic stem cells</a>, <a href="https://publications.waset.org/abstracts/search?q=hematopoietic%20stem%20cell%20transplantation" title=" hematopoietic stem cell transplantation"> hematopoietic stem cell transplantation</a>, <a href="https://publications.waset.org/abstracts/search?q=mesenchymal%20stem%20cells" title=" mesenchymal stem cells"> mesenchymal stem cells</a>, <a href="https://publications.waset.org/abstracts/search?q=umbilical%20cord%20blood" title=" umbilical cord blood"> umbilical cord blood</a> </p> <a href="https://publications.waset.org/abstracts/150887/cord-blood-hematopoietic-stem-cell-expansion-ability-of-mesenchymal-stem-cells-isolated-from-different-sources" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/150887.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">115</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3711</span> Cytotoxic Effects of Engineered Nanoparticles in Human Mesenchymal Stem Cells </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ali%20A.%20Alshatwi">Ali A.

However, there is an ever increasing concern to understand their toxicological effect in human health. Particularly, metal and metal oxide nanoparticles have been used in various sectors including biomedical, food and agriculture. But their impact on human health is yet to be fully understood. In this present investigation, we assessed the toxic effect of engineered nanoparticles (ENPs) including Ag, MgO and Co3O4 nanoparticles (NPs) on human mesenchymal stem cells (hMSC) adopting cell viability and cellular morphological changes as tools The results suggested that silver NPs are more toxic than MgO and Co3O4NPs. The ENPs induced cytotoxicity and nuclear morphological changes in hMSC depending on dose. The cell viability decreases with increase in concentration of ENPs. The cellular morphology studies revealed that ENPs damaged the cells. These preliminary findings have implications for the use of these nanoparticles in food industry with systematic regulations. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cobalt%20oxide" title="cobalt oxide">cobalt oxide</a>, <a href="https://publications.waset.org/abstracts/search?q=human%20mesenchymal%20stem%20cells" title=" human mesenchymal stem cells"> human mesenchymal stem cells</a>, <a href="https://publications.waset.org/abstracts/search?q=MgO" title=" MgO"> MgO</a>, <a href="https://publications.waset.org/abstracts/search?q=silver" title=" silver"> silver</a> </p> <a href="https://publications.waset.org/abstracts/13164/cytotoxic-effects-of-engineered-nanoparticles-in-human-mesenchymal-stem-cells" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/13164.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">388</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3710</span> A Combination of Mesenchymal Stem Cells and Low-Intensity Ultrasound for Knee Meniscus Regeneration: A Preliminary Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Nasb">Mohammad Nasb</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Rehan"> Muhammad Rehan</a>, <a href="https://publications.waset.org/abstracts/search?q=Chen%20Hong"> Chen Hong</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background Meniscus defects critically alter knee function and lead to degenerative changes. Regenerative medicine applications including stem cell transplantation have showed a promising efficacy in finding alternatives to overcome traditional treatment limitations. However, stem cell therapy remains limited due to the substantially reduced viability and inhibitory microenvironment. Since tissue growth and repair are under the control of biochemical and mechanical signals, several approaches have recently been investigated (e.g., low intensity pulsed ultrasound [LIPUS]) to promote the regeneration process. This study employed LIPUS to improve growth and osteogenic differentiation of mesenchymal stem cells derived from human embryonic stem cells to improve the regeneration of meniscus tissue. Methodology: The Mesenchymal stromal cells (MSCs) were transplanted into the epicenter of the injured meniscus in rabbits, which were randomized into two main groups: a treatment group (n=32 New Zealand rabbits) including 4 subgroups of 8 rabbits in each subgroup (LIPUS treatment, MSC treatment, LIPUS with MSC and control), and a second group (n=9) to track implanted cells and their progeny using green fluorescence protein (GFP). GFP consists of the MSC and LIPUS-MSC combination subgroups. Rabbits were then subjected to histological, immunohistochemistry, and MRI assessment. Results: The quantity of the newly regenerated tissue in the combination treatment group that had Ultrasound irradiation after mesenchymal stem cells were better at all end points. Likewise, Tissue quality scores were also greater in knees treated with both approaches compared with controls and single treatment at all end points, achieving significance at twelve and twenty-four weeks [p < 0.05], and [p = 0.008] at twelve weeks. Differentiation into type-I and II collagen-expressing cells were higher in the combination group at up to twenty-four weeks. Conclusions: the combination of mesenchymal stem cells and LIPUS showed greater adhering to the sites of meniscus injury, differentiate into cells resembling meniscal fibrochondrocytes, and improve both quality and quantity of meniscal regeneration. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=stem%20cells" title="stem cells">stem cells</a>, <a href="https://publications.waset.org/abstracts/search?q=regenerative%20medicine" title=" regenerative medicine"> regenerative medicine</a>, <a href="https://publications.waset.org/abstracts/search?q=osteoarthritis" title=" osteoarthritis"> osteoarthritis</a>, <a href="https://publications.waset.org/abstracts/search?q=knee" title=" knee"> knee</a> </p> <a href="https://publications.waset.org/abstracts/108979/a-combination-of-mesenchymal-stem-cells-and-low-intensity-ultrasound-for-knee-meniscus-regeneration-a-preliminary-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/108979.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">119</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3709</span> Studying the Antiapoptotic Activity of Β Cells from Cord Blood Based Mesenchymal Stem Cells as an Approach to Treat Diabetes Mellitus</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Parcha%20Sreenivasa%20Rao">Parcha Sreenivasa Rao</a>, <a href="https://publications.waset.org/abstracts/search?q=P.%20Lakshmi"> P.

The lack of β cells leads to the reduced insulin levels. The β cell death generally occurs due to apoptosis induced by the several cytokines. IL-1β, IFN- ϒ and TNF –α cytokines that are generally cause apoptosis to the β cell. The nutrient based apoptosis is generally seen with high glucose and free fatty acids. It is also noted that the β cell death triggered by Fas ligand and its receptor Fas at the surface of the activated CD8+ T- lymphocytes. Reports also reveal that the β cell apoptosis is under control of the transcription factors NF-kB and STAT- 1. The arresting or opposing of the β cell apoptosis can be overcome by the different growth factors like GLP-1, growth hormone, prolactin, VEGF, Dipeptidyl peptidase-4, Vildagliptin, suberoylanilidehydroxamic acid, trichistatin-A, XIAP, Bcl-2, FGF-21.

Diabetes mellitus is the main cause of premature death, particularly among individuals under the age of 70 years old. Mesenchymal stem cells (MSCs) can release bioactive molecules that promote tissue repair and regeneration. Hence, in this research, we evaluated the potential of autologous adipose-derived mesenchymal stem cells (AD-MSCs) in 40 patients of phase I clinical trial in T2DM with various ages between 30-79 years. AD-MSCs are transferred through catheterization. MSCs were validated by measures of CD105+ and CD34- expression. The result showed that after AD-MSCs transplantation, blood glucose levels (fasting and 2-hour postprandial) and insulin levels were significantly decreasing. Besides that, the level of HbA1c significantly decreased after three months of AD-MSCs injection and increasing level of c-peptide after injection. Thus, we conclude that AD-MSCs injection has the potential for T2DM therapy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=glucose" title="glucose">glucose</a>, <a href="https://publications.waset.org/abstracts/search?q=hyperglycemia" title=" hyperglycemia"> hyperglycemia</a>, <a href="https://publications.waset.org/abstracts/search?q=MSCs" title=" MSCs"> MSCs</a>, <a href="https://publications.waset.org/abstracts/search?q=T2DM" title=" T2DM"> T2DM</a> </p> <a href="https://publications.waset.org/abstracts/171671/the-ability-of-adipose-derived-mesenchymal-stem-cells-for-diabetes-mellitus-type-2-treatment" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/171671.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">81</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3707</span> Stem Cell Fate Decision Depending on TiO2 Nanotubular Geometry</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jung%20Park">Jung Park</a>, <a href="https://publications.waset.org/abstracts/search?q=Anca%20Mazare"> Anca Mazare</a>, <a href="https://publications.waset.org/abstracts/search?q=Klaus%20Von%20Der%20Mark"> Klaus Von Der Mark</a>, <a href="https://publications.waset.org/abstracts/search?q=Patrik%20Schmuki"> Patrik Schmuki </a> </p> <p class="card-text"><strong>Abstract:</strong></p> In clinical application of TiO2 implants on tooth and hip replacement, migration, adhesion and differentiation of neighboring mesenchymal stem cells onto implant surfaces are critical steps for successful bone regeneration. In a recent decade, accumulated attention has been paid on nanoscale electrochemical surface modifications on TiO2 layer for improving bone-TiO2 surface integration. We generated, on titanium surfaces, self-assembled layers of vertically oriented TiO2 nanotubes with defined diameters between 15 and 100 nm and here we show that mesenchymal stem cells finely sense TiO2 nanotubular geometry and quickly decide their cell fate either to differentiation into osteoblasts or to programmed cell death (apoptosis) on TiO2 nanotube layers. These cell fate decisions are critically dependent on nanotube size differences (15-100nm in diameters) of TiO2 nanotubes sensing by integrin clustering. We further demonstrate that nanoscale topography-sensing is feasible not only in mesenchymal stem cells but rather seems as generalized nanoscale microenvironment-cell interaction mechanism in several cell types composing bone tissue network including osteoblasts, osteoclast, endothelial cells and hematopoietic stem cells. Additionally we discuss the synergistic effect of simultaneous stimulation by nanotube-bound growth factor and nanoscale topographic cues on enhanced bone regeneration. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=TiO2%20nanotube" title="TiO2 nanotube">TiO2 nanotube</a>, <a href="https://publications.waset.org/abstracts/search?q=stem%20cell%20fate%20decision" title=" stem cell fate decision"> stem cell fate decision</a>, <a href="https://publications.waset.org/abstracts/search?q=nano-scale%20microenvironment" title=" nano-scale microenvironment"> nano-scale microenvironment</a>, <a href="https://publications.waset.org/abstracts/search?q=bone%20regeneration" title=" bone regeneration"> bone regeneration</a> </p> <a href="https://publications.waset.org/abstracts/12191/stem-cell-fate-decision-depending-on-tio2-nanotubular-geometry" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/12191.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">432</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3706</span> Culture of Human Mesenchymal Stem Cells Culture in Xeno-Free Serum-Free Culture Conditions on Laminin-521</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Halima%20Albalushi">Halima Albalushi</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohadese%20Boroojerdi"> Mohadese Boroojerdi</a>, <a href="https://publications.waset.org/abstracts/search?q=Murtadha%20Alkhabori"> Murtadha Alkhabori</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: Maintenance of stem cell properties during culture necessitates the recreation of the natural cell niche. Studies reported the promising outcome of mesenchymal stem cells (MSC) properties maintenance after using extracellular matrix such as CELLstart™, which is the recommended coating material for stem cells cultured in serum-free and xeno-free conditions. Laminin-521 is known as a crucial adhesion protein, which is found in natural stem cell niche, and plays an important role in facilitating the maintenance of self-renewal, pluripotency, standard morphology, and karyotype of human pluripotent stem cells (PSCs). The aim of this study is to investigate the effects of Laminin-521 on human umbilical cord-derived mesenchymal stem cells (UC-MSC) characteristics as a step toward clinical application. Methods: Human MSC were isolated from the umbilical cord via the explant method. Umbilical cord-derived-MSC were cultured in serum-free and xeno-free conditions in the presence of Laminin-521 for six passages. Cultured cells were evaluated by morphology and expansion index for each passage. Phenotypic characterization of UC-MSCs cultured on Laminin-521 was evaluated by assessment of cell surface markers. Results: Umbilical cord derived-MSCs formed small colonies and expanded as a homogeneous monolayer when cultured on Laminin-521. Umbilical cord derived-MSCs reached confluence after 4 days in culture. No statistically significant difference was detected in all passages when comparing the expansion index of UC-MSCs cultured on LN-521 and CELLstart™. Phenotypic characterization of UC-MSCs cultured on LN-521 using flow cytometry revealed positive expression of CD73, CD90, CD105 and negative expression of CD34, CD45, CD19, CD14 and HLA-DR.Conclusion: Laminin-521 is comparable to CELLstart™ in supporting UC-MSCs expansion and maintaining their characteristics during culture in xeno-free and serum-free culture conditions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=mesenchymal%20stem%20cells" title="mesenchymal stem cells">mesenchymal stem cells</a>, <a href="https://publications.waset.org/abstracts/search?q=culture" title=" culture"> culture</a>, <a href="https://publications.waset.org/abstracts/search?q=laminin-521" title=" laminin-521"> laminin-521</a>, <a href="https://publications.waset.org/abstracts/search?q=xeno-free%20serum-free" title=" xeno-free serum-free"> xeno-free serum-free</a> </p> <a href="https://publications.waset.org/abstracts/169207/culture-of-human-mesenchymal-stem-cells-culture-in-xeno-free-serum-free-culture-conditions-on-laminin-521" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/169207.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">74</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3705</span> Benign Osteoblastoma of the Mandible Resection and Replacement of the Defects with Decellularized Cattle Bone Scaffold with Mesenchymal Bone Marrow Stem Cells</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=K.%20Mardaleishvili">K.

After expansion of mesenchymal stem cells, differentiation of these cells was done by three different protocols (the one-step protocol was used conophylline protein, the two steps protocol was depending on trichostatin-A, and the three-step protocol was started by beta-mercaptoethanol). Evaluation of gene expression was carried out by real-time PCR: Pancreatic endocrine genes, transcription factors, glucose transporter, precursor markers, pancreatic enzymes, proteolytic cleavage, extracellular matrix and cell surface protein. Quantitation of insulin secretion was detected by immunofluorescence technique in 24-well plate. Most of the genes studied were up-regulated in the in vitro differentiated cells, and also insulin production was observed in the three independent protocols. There were some slight increases in expression of endocrine mRNA of two-step protocol and its insulin production. So, the two-step protocol was showed a more efficient in expressing of pancreatic endocrine genes and its insulin production than the other two protocols. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=mesenchymal%20stem%20cells" title="mesenchymal stem cells">mesenchymal stem cells</a>, <a href="https://publications.waset.org/abstracts/search?q=insulin%20producing%20cells" title=" insulin producing cells"> insulin producing cells</a>, <a href="https://publications.waset.org/abstracts/search?q=conophylline%20protein" title=" conophylline protein"> conophylline protein</a>, <a href="https://publications.waset.org/abstracts/search?q=trichostatin-A" title=" trichostatin-A"> trichostatin-A</a>, <a href="https://publications.waset.org/abstracts/search?q=beta-mercaptoethanol" title=" beta-mercaptoethanol"> beta-mercaptoethanol</a>, <a href="https://publications.waset.org/abstracts/search?q=gene%20expression" title=" gene expression"> gene expression</a>, <a href="https://publications.waset.org/abstracts/search?q=immunofluorescence%20technique" title=" immunofluorescence technique"> immunofluorescence technique</a> </p> <a href="https://publications.waset.org/abstracts/85954/evaluation-of-gene-expression-after-in-vitro-differentiation-of-human-bone-marrow-derived-stem-cells-to-insulin-producing-cells" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/85954.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">215</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3703</span> The Using of Hybrid Superparamagnetic Magnetite Nanoparticles (Fe₃O₄)- Graphene Oxide Functionalized Surface with Collagen, to Target the Cancer Stem Cell</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Khalaf%20Reyad%20Raslan">Ahmed Khalaf Reyad Raslan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Cancer stem cells (CSCs) describe a class of pluripotent cancer cells that behave analogously to normal stem cells in their ability to differentiate into the spectrum of cell types observed in tumors.

HUCB contain different types of progenitor cells which could differentiate into hepatocytes. Aims: To investigate the potential of rat's liver damage repair using human umbilical cord mesenchymal stem cells (hUCMSCs). We investigated the feasibility for hUCMSCs in recovery from liver damage. Moreover, investigating fibrotic liver repair and using the CCl4-induced model for liver damage in the rat. Methods: Rats were injected with 0.5 ml/kg CCl4 to induce liver damage and progressive liver fibrosis. hUCMSCs were injected into the rats through the tail vein; Stem cells were transplanted at a dose of 1×106 cells/rat after 72 hours of CCl4 injection without receiving any immunosuppressant. After (6 and 8 weeks) of transplantation, blood samples were collected to assess liver functions (ALT, AST, GGT and ALB) and level of Procollagen III as a liver fibrosis marker. In addition, hepatic tissue regeneration was assessed histopathologically and immunohistochemically using antihuman monoclonal antibodies against CD34, CK19 and albumin. Results: Biochemical and histopathological analysis showed significantly increased recovery from liver damage in the transplanted group. In addition, HUCB stem cells transdifferentiated into functional hepatocytes in rats with hepatic injury which results in improving liver structure and function. Conclusion: Our findings suggest that transplantation of hUCMSCs may be a novel therapeutic approach for treating liver fibrosis. Therefore, hUCMSCs are a potential option for treatment of liver cirrhosis. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=carbon%20tetra%20chloride" title="carbon tetra chloride">carbon tetra chloride</a>, <a href="https://publications.waset.org/abstracts/search?q=liver%20fibrosis" title=" liver fibrosis"> liver fibrosis</a>, <a href="https://publications.waset.org/abstracts/search?q=mesenchymal%20stem%20cells" title=" mesenchymal stem cells"> mesenchymal stem cells</a>, <a href="https://publications.waset.org/abstracts/search?q=rat" title=" rat"> rat</a> </p> <a href="https://publications.waset.org/abstracts/27746/comparative-stem-cells-therapy-for-regeneration-of-liver-fibrosis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/27746.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">342</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3701</span> Wound Healing Potential and Comparison of Mummy Substance Effect on Adipose and Wharton’s Jelly-Derived Mesenchymal Stem Cells Co-Cultured with Human Fibroblast</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sepideh%20Hassanpour%20Khodaei">Sepideh Hassanpour Khodaei</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background/Objectives: The purpose of this study is to evaluate the effect of mummy substances on two issues of proliferation and production of matrix protein synthesis in wound healing. Methods: The methodology used for this aim involves isolating mesenchymal stem cells and human fibroblasts procured at Pastor Institute, Iran. The cells were treated with mummy substances separately and co-cultured between ASCs and WJSCs, and fibroblasts. Proliferation was assessed by Ki67 method in monolayer conditions. Synthesis of components of extracellular matrix (ECM) such as collagen type I, type III, and fibronectin 1 (FN1) was determined by qPCR. Results: The effects of adipocyte stem cells (ASCs), Wharton Jelly Stem Cells (WJSCs), and Mummy material on fibroblast proliferation and migration were evaluated. The present finding underlined the importance of Mummy material, ASCs, and WJSCs in the proliferation and migration of fibroblast cells. Furthermore, the expression of collagen I, III, and FN1 was increased in the presence of the above material and cells.

Additionally, it has been reported that the angiogenic ability of subcutaneous AT-MSCs (SAT-MSCs) was impaired in the AS patients. However, up to now, the effects of AS on the characteristics and function of PVAT-MSCs have not been clarified yet. In the present study, we analyzed the AS microenvironment effects on the characteristics and function of AT-MSCs. We found that there was no significant difference in cellular morphology and differentiation ability between SAT-MSCs and PVAT-MSCs in AS patients. However, the proliferation of AS-derived PVAT-MSCs was less than those of AS-derived SAT-MSCs. Importantly, the migration of AS-derived PVAT-MSCs was faster than AS-derived SAT-MSCs. Of note, AS-derived PVAT-MSCs showed the upregulation of SDF1, which is related to the homing, and VEGF, which is related to the angiogenesis compared to those of AS-derived SAT-MSCs. Consistent with these results, AS-derived PVAT-MSCs showed the higher ability to recruit EPCs and ECs than AS-derived SAT-MSCs. In addition, EPCs and ECs which cultured in the presence of AS-derived PVAT-MSC conditioned medium showed the higher angiogenic function of the tube formation compared to those cultured in AS-derived SAT-MSC conditioned medium. This result suggests that the higher paracrine effects of AS-derived PVAT-MSCs support the angiogenic function of the target cells. Our data showed the different characteristics and functions of AT-MSCs derived from different sources of tissues. Under the AS microenvironment, it seems that the characteristics and functions of PVAT-MSCs might reflect the progression of AS. Further study will be necessary to clarify the mechanism in the future. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=atherosclerosis" title="atherosclerosis">atherosclerosis</a>, <a href="https://publications.waset.org/abstracts/search?q=mesenchymal%20stem%20cells" title=" mesenchymal stem cells"> mesenchymal stem cells</a>, <a href="https://publications.waset.org/abstracts/search?q=perivascular%20adipose%20tissue" title=" perivascular adipose tissue"> perivascular adipose tissue</a>, <a href="https://publications.waset.org/abstracts/search?q=subcutaneous%20adipose%20tissue" title=" subcutaneous adipose tissue"> subcutaneous adipose tissue</a> </p> <a href="https://publications.waset.org/abstracts/101561/analysis-of-adipose-tissue-derived-mesenchymal-stem-cells-under-atherosclerosis-microenvironment" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/101561.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">161</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3699</span> System for Mechanical Stimulation of the Mesenchymal Stem Cells Supporting Differentiation into Osteogenic Cells</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jana%20Stepanovska">Jana Stepanovska</a>, <a href="https://publications.waset.org/abstracts/search?q=Roman%20Matejka"> Roman Matejka</a>, <a href="https://publications.waset.org/abstracts/search?q=Jozef%20Rosina"> Jozef Rosina</a>, <a href="https://publications.waset.org/abstracts/search?q=Marta%20Vandrovcova"> Marta Vandrovcova</a>, <a href="https://publications.waset.org/abstracts/search?q=Lucie%20Bacakova"> Lucie Bacakova</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The aim of this study was to develop a system for mechanical and also electrical stimulation controlling in vitro osteogenesis under conditions more similar to the in vivo bone microenvironment than traditional static cultivation, which would achieve good adhesion, growth and other specific behaviors of osteogenic cells in cultures. An engineered culture system for mechanical stimulation of the mesenchymal stem cells on the charged surface was designed. The bioreactor allows efficient mechanical loading inducing an electrical response and perfusion of the culture chamber with seeded cells. The mesenchymal stem cells were seeded to specific charged materials, like polarized hydroxyapatite (Hap) or other materials with piezoelectric and ferroelectric features, to create electrical potentials for stimulating of the cells. The material of the matrix was TiNb alloy designed for these purposes, and it was covered by BaTiO3 film, like a kind of piezoelectric material. The process of mechanical stimulation inducing electrical response is controlled by measuring electrical potential in the chamber. It was performed a series of experiments, where the cells were seeded, perfused and stimulated up to 48 hours under different conditions, especially pressure and perfusion. The analysis of the proteins expression was done, which demonstrated the effective mechanical and electrical stimulation. The experiments demonstrated effective stimulation of the cells in comparison with the static culture.

MSC-based therapies have emerged as a promising strategy for various diseases such as cancer, tissue regeneration, or immunologic/inflammatory-related diseases. This study evaluated the clinical application of MSCs for cancer therapy in trials registered on Clinical Trial as of July 2022. The results showed 40 clinical trials used MSCs in various cancer conditions. 62% of trials used MSCs for therapeutic purposes to minimize the side effects of cancer treatment. Besides, 38% of trials were focused on using MSCs as a therapeutic agent to treat cancer directly. Most trials (38/40) are ongoing phase I/II, and 2 are entering phase III. 84% of trials used allogeneic MSCs compared with 13% using autologous sources and 3% using both. 25/40 trials showed participants received a single dose of MSCs, while the most times were 12 times in a pancreatic cancer treatment trial. Conclusion: MSC-based therapy for cancer in clinical trials should be applied to (1) minimize the side effects of oncological treatments and (2) directly affect the tumor via selectively delivering anti-cancer payloads to tumor cells. Allogeneic MSCs are a priority selected in clinical cancer therapy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=mesenchymal%20stem%20cells" title="mesenchymal stem cells">mesenchymal stem cells</a>, <a href="https://publications.waset.org/abstracts/search?q=MSC-based%20therapy" title=" MSC-based therapy"> MSC-based therapy</a>, <a href="https://publications.waset.org/abstracts/search?q=cancer%20condition" title=" cancer condition"> cancer condition</a>, <a href="https://publications.waset.org/abstracts/search?q=cancer%20treatment" title=" cancer treatment"> cancer treatment</a>, <a href="https://publications.waset.org/abstracts/search?q=clinical%20trials" title=" clinical trials"> clinical trials</a> </p> <a href="https://publications.waset.org/abstracts/164222/clinical-application-of-mesenchymal-stem-cells-for-cancer-therapy-a-review-of-registered-clinical-trials" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/164222.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">92</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3697</span> Effect of Locally Injected Mesenchymal Stem Cells on Bone Regeneration of Rat Calvaria Defects</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gileade%20P.%20Freitas">Gileade P.

However, the extent of injury may exceed the inherent tissue regeneration capability demanding some kind of additional intervention. In this scenario, cell therapy has emerged as a promising alternative to treat challenging bone defects. This study aimed at evaluating the effect of local injection of bone marrow-derived mesenchymal stem cells (BM-MSCs) and adipose tissue-derived mesenchymal stem cells (AT-MSCs) on bone regeneration of rat calvaria defects. BM-MSCs and AT-MSCs were isolated and characterized by expression of surface markers; cell viability was evaluated after injection through a 21G needle. Defects of 5 mm in diameter were created in calvaria and after two weeks a single injection of BM-MSCs, AT-MSCs or vehicle-PBS without cells (Control) was carried out. Cells were tracked by bioluminescence and at 4 weeks post-injection bone formation was evaluated by micro-computed tomography (μCT) and histology, nanoindentation, and through gene expression of bone remodeling markers. The data were evaluated by one-way analysis of variance (p≤0.05). BM-MSCs and AT-MSCs presented characteristics of mesenchymal stem cells, kept viability after passing through a 21G needle and remained in the defects until day 14. In general, injection of both BM-MSCs and AT-MSCs resulted in higher bone formation compared to Control. Additionally, this bone tissue displayed elastic modulus and hardness similar to the pristine calvaria bone. The expression of all evaluated genes involved in bone formation was upregulated in bone tissue formed by BM-MSCs compared to AT-MSCs while genes involved in bone resorption were upregulated in AT-MSCs-formed bone. We show that cell therapy based on the local injection of BM-MSCs or AT-MSCs is effective in delivering viable cells that displayed local engraftment and induced a significant improvement in bone healing. Despite differences in the molecular cues observed between BM-MSCs and AT-MSCs, both cells were capable of forming bone tissue at comparable amounts and properties. These findings may drive cell therapy approaches toward the complete bone regeneration of challenging sites. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cell%20therapy" title="cell therapy">cell therapy</a>, <a href="https://publications.waset.org/abstracts/search?q=mesenchymal%20stem%20cells" title=" mesenchymal stem cells"> mesenchymal stem cells</a>, <a href="https://publications.waset.org/abstracts/search?q=bone%20repair" title=" bone repair"> bone repair</a>, <a href="https://publications.waset.org/abstracts/search?q=cell%20culture" title=" cell culture"> cell culture</a> </p> <a href="https://publications.waset.org/abstracts/103816/effect-of-locally-injected-mesenchymal-stem-cells-on-bone-regeneration-of-rat-calvaria-defects" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/103816.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">184</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3696</span> Stroma-Providing Activity of Adipose Derived Mesenchymal Stromal Cells in Tissue-Related O2 Microenvironment</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=P.%20I.%20Bobyleva">P.

We showed that 72-hour interaction of MSCs with cord blood mononuclear cells (MNCs) in vitro at atmospheric (20%) and low (5%) O2 conditions increased the expression of ICAM-1, HCAM (at the beginning of interaction) on MSCs. Viability of MSCs and MNCs were maintained at high level. Adhesion of MNCs to MSCs was faster at 20% O2. MSCs promoted the proliferation of adhered MNCs to form the suspension containing great number of hematopoietic colony-forming units, and this effect was more pronounced at 5% O2. Thus, adipose-derived MSCs supplied sufficient stromal support to cord blood MNCs both at 20% and 5% О2, providing their adhesion with further expansion of new generation of different hematopoietic lineages. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hematopoietic%20stem%20and%20progenitor%20cells" title="hematopoietic stem and progenitor cells">hematopoietic stem and progenitor cells</a>, <a href="https://publications.waset.org/abstracts/search?q=mesenchymal%20stromal%20cells" title=" mesenchymal stromal cells"> mesenchymal stromal cells</a>, <a href="https://publications.waset.org/abstracts/search?q=tissue-related%20oxygen" title=" tissue-related oxygen"> tissue-related oxygen</a>, <a href="https://publications.waset.org/abstracts/search?q=adipose%20tissue" title=" adipose tissue"> adipose tissue</a> </p> <a href="https://publications.waset.org/abstracts/13129/stroma-providing-activity-of-adipose-derived-mesenchymal-stromal-cells-in-tissue-related-o2-microenvironment" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/13129.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">418</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3695</span> Evaluation of Cytotoxic Effect of Mitoxantrone Conjugated Magnetite Nanoparticles and Graphene Oxide-Magnetite Nanocomposites on Mesenchymal Stem Cells</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abbas%20Jafarizad">Abbas Jafarizad</a>, <a href="https://publications.waset.org/abstracts/search?q=Duygu%20Ekinci"> Duygu Ekinci</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this work targeted drug delivery is proposed to decrease adverse effect of drugs with concomitant reduces in consumption and treatment outgoings. Nanoparticles (NPs) can be prepared from a variety of materials such as lipid, biodegradable polymer that prevent the drugs cytotoxicity in healthy cells, etc. One of the most important drugs used in chemotherapy is mitoxantrone (MTX) which prevents cell proliferation by inhibition of topoisomerase II and DNA repair; however, it is not selective and has some serious side effects. In this study, mentioned aim is achieved by using several nanocarriers like magnetite (Fe3O4) and their composites with magnetic graphene oxide (Fe3O4@GO). Also, cytotoxic potential of Fe3O4, Fe3O4-MTX, and Fe3O4@GO-MTX nanocomposite were evaluated on mesenchymal stem cells (MSCs). In this study, we reported the synthesis of monodisperse Fe3O4 NPs and Fe3O4@GO nanocomposite and their structures were investigated by using field emission scanning electron microscope (FESEM), Fourier transform infrared (FTIR) spectra, atomic force microscopy (AFM), Brauneur Emmet Teller (BET) isotherm and contact angle studies. Moreover, we used 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay to evaluate cytotoxic effects of MTX, Fe3O4 NPs, Fe3O4-MTX and Fe3O4@GO-MTX nanocomposite on MSCs. The in-vitro MTT results indicated that all concentrations of MTX and Fe3O4@GO-MTX nanocomposites showed cytotoxic effects while all concentrations of Fe3O4 NPs and Fe3O4-MTX NPs did not show any cytotoxic effect on stem cells. The results from this study indicated that using Fe3O4 NPs as anticancer drug delivery systems could be a trustworthy method for cancer treatment. But for reaching excellent and accurate results, further investigation is necessary. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=mitoxantrone" title="mitoxantrone">mitoxantrone</a>, <a href="https://publications.waset.org/abstracts/search?q=magnetite" title=" magnetite"> magnetite</a>, <a href="https://publications.waset.org/abstracts/search?q=magnetic%20graphene%20oxide" title=" magnetic graphene oxide"> magnetic graphene oxide</a>, <a href="https://publications.waset.org/abstracts/search?q=MTT%20assay" title=" MTT assay"> MTT assay</a>, <a href="https://publications.waset.org/abstracts/search?q=mesenchymal%20stem%20cells" title=" mesenchymal stem cells"> mesenchymal stem cells</a> </p> <a href="https://publications.waset.org/abstracts/66115/evaluation-of-cytotoxic-effect-of-mitoxantrone-conjugated-magnetite-nanoparticles-and-graphene-oxide-magnetite-nanocomposites-on-mesenchymal-stem-cells" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/66115.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">272</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3694</span> Osteogenesis in Thermo-Sensitive Hydrogel Using Mesenchymal Stem Cell Derived from Human Turbinate</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20Reum%20Son">A.

As a supporter of stem cells, in situ-forming hydrogels with growth factors and cells appear to be a promising approach in tissue engineering. To examine osteogenic differentiation of hTMSCs which is one of mesenchymal stem cells in vivo in an injectable hydrogel, we use a methoxy polyethylene glycol-polycaprolactone blockcopolymer (MPEG-PCL) solution with osteogenic factors. We synthesized MPEG-PCL hydrogel and measured viscosity to check sol-gel transition. In order to demonstrate osteogenic ability of hTMSCs, we conducted in vitro osteogenesis experiment. Then, to confirm the cell cytotoxicity, we performed WST-1 with hTMSCs and MPEG-PCL. As the result of in vitro experiment, we implanted cell and hydrogel mixture into animal model and checked degree of osteogenesis with histological analysis and amount of expression genes. Through these experimental data, MPEG-PCL hydrogel has sol-gel transition in temperature change and is biocompatible with stem cells. In histological analysis and gene expression, hTMSCs are very good source of osteogenesis with hydrogel and will use it to tissue engineering as important treatment method. hTMSCs could be a good adult stem cell source for usability of isolation and high proliferation. When hTMSCs are used as cell therapy method with in situ-formed hydrogel, they may provide various benefits like a noninvasive alternative for bone tissue engineering applications. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=injectable%20hydrogel" title="injectable hydrogel">injectable hydrogel</a>, <a href="https://publications.waset.org/abstracts/search?q=stem%20cell" title=" stem cell"> stem cell</a>, <a href="https://publications.waset.org/abstracts/search?q=osteogenic%20differentiation" title=" osteogenic differentiation"> osteogenic differentiation</a>, <a href="https://publications.waset.org/abstracts/search?q=tissue%20engineering" title=" tissue engineering"> tissue engineering</a> </p> <a href="https://publications.waset.org/abstracts/9285/osteogenesis-in-thermo-sensitive-hydrogel-using-mesenchymal-stem-cell-derived-from-human-turbinate" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/9285.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">447</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3693</span> In vitro Regeneration of Neural Cells Using Human Umbilical Cord Derived Mesenchymal Stem Cells</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Urvi%20Panwar">Urvi Panwar</a>, <a href="https://publications.waset.org/abstracts/search?q=Kanchan%20Mishra"> Kanchan Mishra</a>, <a href="https://publications.waset.org/abstracts/search?q=Kanjaksha%20Ghosh"> Kanjaksha Ghosh</a>, <a href="https://publications.waset.org/abstracts/search?q=ShankerLal%20Kothari"> ShankerLal Kothari</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Day-by-day the increasing prevalence of neurodegenerative diseases have become a global issue to manage them by medical sciences. The adult neural stem cells are rare and require an invasive and painful procedure to obtain it from central nervous system. Mesenchymal stem cell (MSCs) therapies have shown remarkable application in treatment of various cell injuries and cell loss. MSCs can be derived from various sources like adult tissues, human bone marrow, umbilical cord blood and cord tissue. MSCs have similar proliferation and differentiation capability, but the human umbilical cord-derived mesenchymal stem cells (hUCMSCs) are proved to be more beneficial with respect to cell procurement, differentiation to other cells, preservation, and transplantation. Material and method: Human umbilical cord is easily obtainable and non-controversial comparative to bone marrow and other adult tissues. The umbilical cord can be collected after delivery of baby, and its tissue can be cultured using explant culture method. Cell culture medium such as DMEMF12+10% FBS and DMEMF12+Neural growth factors (bFGF, human noggin, B27) with antibiotics (Streptomycin/Gentamycin) were used to culture and differentiate mesenchymal stem cells into neural cells, respectively. The characterisations of MSCs were done with Flow Cytometer for surface markers CD90, CD73 and CD105 and colony forming unit assay. The differentiated various neural cells will be characterised by fluorescence markers for neurons, astrocytes, and oligodendrocytes; quantitative PCR for genes Nestin and NeuroD1 and Western blotting technique for gap43 protein. Result and discussion: The high quality and number of MSCs were isolated from human umbilical cord via explant culture method. The obtained MSCs were differentiated into neural cells like neurons, astrocytes and oligodendrocytes. The differentiated neural cells can be used to treat neural injuries and neural cell loss by delivering cells by non-invasive administration via cerebrospinal fluid (CSF) or blood. Moreover, the MSCs can also be directly delivered to different injured sites where they differentiate into neural cells. Therefore, human umbilical cord is demonstrated to be an inexpensive and easily available source for MSCs. Moreover, the hUCMSCs can be a potential source for neural cell therapies and neural cell regeneration for neural cell injuries and neural cell loss. This new way of research will be helpful to treat and manage neural cell damages and neurodegenerative diseases like Alzheimer and Parkinson. Still the study has a long way to go but it is a promising approach for many neural disorders for which at present no satisfactory management is available. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bone%20marrow" title="bone marrow">bone marrow</a>, <a href="https://publications.waset.org/abstracts/search?q=cell%20therapy" title=" cell therapy"> cell therapy</a>, <a href="https://publications.waset.org/abstracts/search?q=explant%20culture%20method" title=" explant culture method"> explant culture method</a>, <a href="https://publications.waset.org/abstracts/search?q=flow%20cytometer" title=" flow cytometer"> flow cytometer</a>, <a href="https://publications.waset.org/abstracts/search?q=human%20umbilical%20cord" title=" human umbilical cord"> human umbilical cord</a>, <a href="https://publications.waset.org/abstracts/search?q=mesenchymal%20stem%20cells" title=" mesenchymal stem cells"> mesenchymal stem cells</a>, <a href="https://publications.waset.org/abstracts/search?q=neurodegenerative%20diseases" title=" neurodegenerative diseases"> neurodegenerative diseases</a>, <a href="https://publications.waset.org/abstracts/search?q=neuroprotective" title=" neuroprotective"> neuroprotective</a>, <a href="https://publications.waset.org/abstracts/search?q=regeneration" title=" regeneration"> regeneration</a> </p> <a href="https://publications.waset.org/abstracts/87395/in-vitro-regeneration-of-neural-cells-using-human-umbilical-cord-derived-mesenchymal-stem-cells" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/87395.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">202</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3692</span> The Comparison of the Effects of Adipose-Derived Mesenchymal Stem Cells Delivery by Systemic and Intra-Tracheal Injection on Elastase-Induced Emphysema Model</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Maryam%20Radan">Maryam Radan</a>, <a href="https://publications.waset.org/abstracts/search?q=Fereshteh%20Nejad%20Dehbashi"> Fereshteh Nejad Dehbashi</a>, <a href="https://publications.waset.org/abstracts/search?q=Vahid%20%20Bayati"> Vahid Bayati</a>, <a href="https://publications.waset.org/abstracts/search?q=Mahin%20Dianat"> Mahin Dianat</a>, <a href="https://publications.waset.org/abstracts/search?q=Seyyed%20Ali%20Mard"> Seyyed Ali Mard</a>, <a href="https://publications.waset.org/abstracts/search?q=Zahra%20%20Mansouri"> Zahra Mansouri</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Pulmonary emphysema is a pathological respiratory condition identified by alveolar destruction which leads to limitation of airflow and diminished lung function. A substantial body of evidence suggests that mesenchymal stem cells (MSCs) have the ability to induce tissue repair primarily through a paracrine effect. In this study, we aimed to determine the efficacy of Intratracheal adipose-derived mesenchymal stem cells (ADSCs) therapy in comparison to this approach with that of Intravenous (Systemic) therapy. Fifty adult male Sprague–Dawley rats weighing between 180 and 200 g were used in this experiment. The animals were randomized to Control groups (Intratracheal or Intravenous vehicle), Elastase group (intratracheal administration of porcine pancreatic elastase; 25 U/kg on day 0 and day 10th), Elastase+Intratracheal ADSCs therapy (1x107 Cells, on day 28) and Elastase+Systemic ADSCs therapy (1x107 Cells, on day 28). The rats which not subjected to any treatment, considered as the control. All rats were sacrificed 3 weeks later. Morphometric findings in lung tissues (Mean linear intercept) confirmed the establishment of the emphysema model via alveolar disruption. Contrarily, ADSCs administration partially restored alveolar architecture. These results were associated with improving arterial oxygenation, reducing lung edema, and decreasing lung inflammation with higher significant effects in the Intratracheal therapy route. These results documented that the efficacy of intratracheal ADSCs was comparable with intravenous ADSCs therapy. Accordingly, the obtained data suggested that intratracheal delivery of ADSCs would enhance lung repair in pulmonary emphysema. Moreover, this method provides benefits over a systemic administration, such as the reduction of cell number and the low risk to engraft other organs. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=mesenchymal%20stem%20cell" title="mesenchymal stem cell">mesenchymal stem cell</a>, <a href="https://publications.waset.org/abstracts/search?q=emphysema" title=" emphysema"> emphysema</a>, <a href="https://publications.waset.org/abstracts/search?q=Intratracheal" title=" Intratracheal"> Intratracheal</a>, <a href="https://publications.waset.org/abstracts/search?q=systemic" title=" systemic"> systemic</a> </p> <a href="https://publications.waset.org/abstracts/136584/the-comparison-of-the-effects-of-adipose-derived-mesenchymal-stem-cells-delivery-by-systemic-and-intra-tracheal-injection-on-elastase-induced-emphysema-model" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/136584.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">211</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3691</span> Design and Fabrication of a Scaffold with Appropriate Features for Cartilage Tissue Engineering</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=S.%20S.%20Salehi">S.

An artificial tissue should have some features such as biocompatibility, biodegradation and, enough mechanical properties like the original tissue. In this work, a composite hydrogel is prepared by using natural and synthetic materials that has high porosity. Mechanical properties of different combinations of polymers such as modulus of elasticity were tested, and a hydrogel with good mechanical properties was selected. Bone marrow derived mesenchymal stem cells were also seeded into the pores of the sponge, and the results showed the adhesion and proliferation of cells within the hydrogel after one month. In comparison with previous works, this study offers a new and efficient procedure for the fabrication of cartilage like tissue and further cartilage repair. <p
