Fig. 1. Postnatal development of K5ß1-null mice. Ten d.p.p. K5ß1-null mice have a thinner coat (A), but there is no significant difference in their size or weight (A,B). Transverse sections through the back skin of control (C) and K5ß1-null mice (D) at day 10 p.p. reveal a decreased number of hair follicles in K5ß1-null mice, with concomitant recruitment of macrophages (stained in brown using anti-F4/80 antibody) to the dying follicles (asterisks in D). F, fatty tissue; HF, hair follicle. Scale bars: 200 µm.
