Figure 4 The H&E staining of the skin tissues at days 7, 10, and 12 post-surgery for the CG-control group. Scale bars are 100 µm. A, B, C show the staining sections at day 7, 10 12, respectively. (A1–C1) were from the areas near the wound edge and (A2–C2) were from the areas near the middle of the wounds.
Abbreviations: EL, Epidermis; DL, dermis; S, scab; IC, inflammation-mediating cells; NA, neo-angiogenesis; SG, sebaceous glands.
