Rac1 activation and Gsk3β inactivation recovered Fzd6 junctional localization but not planar asymmetry in Wls-deficient OC. (A–L) Flat-mounted E18.5 wild-type control (A,B), Rac1DA/+ (C,D), Gsk3βcKO (E,F), WlscKO (G,H), WlscKO; Rac1DA/+ (I,J), and WlscKO; Gsk3βcKO (K,L) OC stained for Fzd6 and ZO-1 as indicated. Arrows indicate Fzd6 crescents along the medial borders of OHCs. Arrowheads indicate the inner pillar cell row. Lateral is up. Scale bar: 6 μm. (M) Quantifications of Fzd6 staining along the medial and lateral junctions of OHCs. Numbers of OHCs scored are indicated on the bottom. Color keys for genotypes are indicated on the right. Ns, not significant.
