Fig. 3. Analysis of differentiation markers in K5Cre Jag1^flox/flox, K14CreER Jag1^flox/flox and K14N^ICDOPER skin. (A-O) Back skin of Jag1^flox/flox (A,H,I,L,M), K5Cre Jag1^flox/flox (B,D,J,K,N,O) and 4OHT-treated K14N^ICDOPER (C,E,F,G) mice stained with antibodies to K10 (A-D), CDP (E,H-K), hair keratins (AE13) (F) or trichohyalin (G,L-O). (H,J,L,N) Sections DAPI counterstained (blue). (P-W) Whole mounts of Jag1^flox/flox (P-S), K5Cre Jag1^flox/flox (T-V) and K14CreER Jag1^flox/flox (W) tail epidermis immunolabelled for K14 (P,T,S,W) and CDP (Q,U) or stained with Nile Red (green) and DAPI (blue) (R,V). Dashed lines outline the hair follicles and sebaceous glands. Scale bars: 50 µm in D; 100 µm in A-C,E-W. A, anagen follicles; T, telogen follicles.
