<i>Stmm1</i> congenic mice show a decrease of BrdU-LRCs.

<p>(A) The timetable of BrdU chase experiment. Multiple color bars indicate the mouse hair cycles (orange, anagen; red, catagen; and blue, telogen) and the bold black line below indicates the postnatal days of mice. (B) Representative double-immunostaining patterns of BrdU-LRCs (green) and Keratin 14 (K14) (red) in the skin from a FF homozygous of a congenic line (a) on chromosome 7, (C) a MF heterozygous mouse of a congenic line (a), (D) a FF homozygous mouse of a congenic line having the linkage region on chromosome 4, and (E) a MF heterozygous mice of a congenic line having the same linkage region on chromosome 4. (F) The numbers of BrdU-LRCs per hair follicle in dorsal back skin sections are plotted. The blue bars represent the number of BrdU-LRCs in each congenic line, FF homozygous mice of a congenic line (a) on chromosome 7 (n = 23), MF heterozygous and MM homozygous mice of a congenic line (a) (n = 89), FF homozygous mice of a congenic line having the linkage region on chromosome 4 (n = 27), and MF heterozygous and MM homozygous mice of a congenic line having the same linkage region on chromosome 4 (n = 24). The <i>P</i>-value was calculated for BrdU-LRC number by <i>t</i>-test. Error bar represents standard deviation (S.D.). Abbreviation: Bu, Bulge. Scale bars, 100 µm.
