Fig. 5. Comparison of the first postnatal hair cycle in transgenic and wild-type mice. (A-F) Haematoxylin and Eosin stained sections of skin from 5- (A,B), 7.5- (C,D) and 9- (E,F) week-old wild-type (A,C,E) and K14NLef1 transgenic animals (B,D,F). Scale bar: 200 µm. (G) Schematic representation of the time of onset (start of bar) and duration (bar length) of first postnatal hair cycle in wild-type (wt) and transgenic (tg) animals. The number of animals examined (n) is indicated. See text for explanation of features marked with arrows and arrowheads.
