Fig. 9. Expression of Wnt6, Wnt10a and ß-catenin in wild-type and Ta mutant embryos. (A,B) Wnt6 is expressed in the epithelium of both wild-type and Ta mutant E17 skin. (C-F) Wnt10a transcripts are expressed in the basal epithelial cell layer in wild-type and Ta mutant skin as well as in hair follicles. (G,H) ß-catenin is expressed in the epithelium and underlying mesenchyme in E15 wild-type and Ta mutant skin. (I-L) During later stages, ß-catenin transcripts become strongly upregulated in the hair follicles both in wild type and Ta mutant skin, and expression continues in the basal epithelium as well. Scale bar: 100 µm.
