Effect of CRF on human HF organ culture. Human HFs were incubated with or without CRF at 10− 6 M for 10 days. a Hair shaft elongation was measured on days 0, 2, 5, and 10 using a stereomicroscope. The images were taken at 10× magnification. b Hair cycles of cultured human HFs were scored on day 0, 3 and 6 according to the hair cycle scoring guidelines. The images were taken at 50× magnification. p values of HF elongations compared with those of the control group on the same day, p-values were determined by t-tests, *: p < 0.05, **: p < 0.01
