We generated the conditional knockout (KO) of vinculin in murine skin which results in the loss of bulge stem cell (BuSC) quiescence, and promotes continual cycling of the hair follicles. Surprisingly, we find that the AJs in vinculin KO cells are mechanically weak and impaired in force generation despite increased junctional expression of E-cadherin and a-catenin. Mechanistically, we demonstrate that vinculin functions by keeping a-catenin in a stretched/open conformation, which in turn regulates the retention of YAP1, another potent mechano-transducer and regulator of cell proliferation, at the AJs. Altogether, our data provides definitive mechanistic insights into the hitherto unexplored regulatory link between the mechanical stability of cell junctions and contact inhibition-mediated maintenance of BuSC quiescence.
