Fig. 4. IM facilitates the cycle of hair follicle regeneration in mice.

a Representative images of H&E-stained longitudinal sections of each treated mouse skin on days 0 and 20 after depilation. b Progression of the hair follicle cycle on day 20 was quantitatively evaluated. Individual hair follicles were classified based on the classification by Chase. c Representative images of H&E-stained transverse sections of each treated mouse skin on days 0, 7, 14, and 20 after depilation. d Hair follicles were counted on days 7 and 20. *p < 0.05; **p < 0.01; ***p < 0.001 (Student’s t-test). Scale bar = 200 μm
