Previous endometrial single-cell atlases profiled few donors and lacked consensus in defining cell types. We introduce the Human Endometrial Cell Atlas (HECA), a high-resolution single-cell reference atlas (313,527 cells) combining published and new endometrial single-cell transcriptomics datasets of 63 women with and without endometriosis. HECA assigns consensus and identifies previously unreported cell types, mapped in situ using spatial transcriptomics and validated using a new independent single-nuclei dataset (312,246 nuclei, 63 donors). In the functionalis, we identify intricate stromal–epithelial cell coordination via transforming growth factor beta (TGFβ) signaling. In the basalis, we define signaling between fibroblasts and an epithelial population expressing progenitor markers. Integration of HECA with large-scale endometriosis genome-wide association study data pinpoints decidualized stromal cells and macrophages as most likely dysregulated in endometriosis. The HECA is a valuable resource for studying endometrial physiology and disorders, and for guiding microphysiological in vitro systems development.</p> <p> DOI: 10.1038/s41588-024-01873-w</p> <p> Source: <a href="https://www.nature.com/articles/s41588-024-01873-w">https://www.nature.com/articles/s41588-024-01873-w</a></p> </p> <div class="remarks">期刊信息</div> <div class="dd"><p> <span style="font-weight: bold;">Nature Genetics：</span>《自然—遗传学》，创刊于1992年。隶属于施普林格·自然出版集团，最新IF：41.307<br /> <span style="font-weight: bold;">官方网址：</span><a href="https://www.nature.com/ng/" target="_blank">https://www.nature.com/ng/</a><br /> <span style="font-weight: bold;">投稿链接：</span><a href="https://mts-ng.nature.com/cgi-bin/main.plex" target="_blank">https://mts-ng.nature.com/cgi-bin/main.plex</a></p> </div> </div> </div> <style> #footer{ background:#890f0e; text-align:center; padding:10px; color:#FFF; font-size:12px;} #footer a{color:#FFF; font-size:12px;} </style> <div id="footer"><a href="http://www.sciencenet.cn/aboutus/" target="_blank">关于我们</a> | <a href="http://www.sciencenet.cn/shengming.aspx" target="_blank">网站声明</a> | <a href="http://www.sciencenet.cn/tiaokuang.aspx" target="_blank">服务条款</a> | <a href="http://www.sciencenet.cn/contact.aspx" target="_blank">联系方式</a> | <a href="http://www.sciencenet.cn/RSS.aspx">RSS</a> | <a href="mailto:jubao@stimes.cn">举报</a> | <a href="https://stimes.sciencenet.cn/">中国科学报社</a> <br> <a href="https://beian.miit.gov.cn" target="_blank" > 京ICP备07017567号-12 </a> 互联网新闻信息服务许可证10120230008  京公网安备 11010802032783<br>Copyright @ 2007-<script type="text/javascript">var Date22 = new Date();var year22 = Date22.getFullYear();document.write(year22);</script> 中国科学报社 All Rights Reserved<br> 地址：北京市海淀区中关村南一条乙三号  邮箱：blog@stimes.cn <br> <span style="display:none"> <script type="text/javascript"> var _bdhmProtocol = (("https:" == document.location.protocol) ?
