Fig. 7
(a) Histological analysis of wound tissue sections on days 6 and 14 after treatment with PBS or SMH. Blue arrows indicate the original epidermal layer at the wound edges. Red arrows highlight newly formed epidermis covering the wound bed. On day 14, SMH-treated wounds show a greater extent of re-epithelialization compared to the PBS control group as evidenced by the presence of more continuous and thicker newly generated epidermal tissue (red arrows). (b), (c) and (d) are magnified images of un-healed tissue (black rectangle), original epidermal layer (blue rectangle) and newly formed epidermis (red rectangle). Scale bar = 2.5 mm.
