The hair cycle was synchronized to anagen phase by wax depilation, and tamoxifen was topically applied to the dorsal skin of <i>Map3k7</i><sup>fl/fl</sup>K14-Cre-ER<sup>T2</sup>mice to delete TAK1. As controls, <i>Map3k7</i><sup>fl/fl</sup> mice or <i>Map3k7</i><sup>fl/fl</sup>K14-Cre-ER<sup>T2</sup> mice were treated with tamoxifen or ethanol, respectively. (B) Clinical appearance at the indicated time point after the depilation. At 2 weeks, hair shaft formation was noted in the control mice, while hair shaft growth was not seen in the tamoxifen-treated <i>Map3k7</i><sup>fl/fl</sup>K14-Cre-ER<sup>T2</sup> mice. (C) Histological analysis at the indicated time point after the depilation. Anagen progression was severely delayed in TAK1-deleted mice at 1–3 weeks.
