Consistent with the predominantly nuclear localization of YAP/TAZ in SC‐containing compartments during HF growth,13, 123, 144, 145, 146 tamoxifen‐induced depletion of Yap and Taz in Krt5‐expressing epidermal stem/progenitor cells (K5‐CreERT/Yap/Taz) of adult mice led to progressive hair loss beginning 2 weeks after the first tamoxifen injections, while only causing a moderate reduction of basal cell proliferation in the IFE.13 Here, KRT5 is linked to hydrops fetalis.
