In vivo hair growth evaluation and histological study in C57BL/6 mice of wound healing models. A. Representative photographic images of the wounded skin after different treatments on day 0, 3, 5, 7, 9, 11, 13, 15, and 17, respectively. The control group (Ctrl) was mice without treatment. B. Quantification of the wound area rate in each group on day 0, 3, 5, 7, 9, and 11. C. Images showing H & E staining (upper row), anti-CD31 immunohistochemistry staining (middle row), and anti-Ki67 immunohistochemistry staining (lower row) in different groups on day 17 (hair regrowth). D. Quantification of follicle number per field using H & E staining. E. Quantification of capillary density using anti-CD31 staining. F. Quantification of proliferating cell rate using anti-Ki67 staining. n = 3, *p < 0.05, NS refers to no significance.
