Figure 5. Melanin-particle-containing hair follicles and epidermal cells in Vitiligo mice. a). HCJA121 and HCJA404 significantly increased the number of melanin-containing epidermal cells in the skin of vitiligo mice. The black arrows indicate epidermal cells that contain melanin particles; magnification, 200×; b). The compounds could clearly increase the melanin-particle-containing hair follicles in the skin of vitiligo mice; magnification, 200×. n = 12 mice per group.
