Postoperative skin wound. (a) to (l) After 7, 14 and 21 days, there were no visible signs of wound inflammation in all four groups, the graft was in close contact with the wound, and the wound of Group D was dry and clean with red granulation. (m) Wound healing rates of Groups A to C were fast after 7 days, with the graft absorption speed in Group A being fastest at 14 and 21 days. In Group A, the graft combined solidly with its surrounding tissue, and the wound healing rate was significantly higher than in other groups. *P <0.05. Gel-C6S-HA, gelatin–chondroitin-6-sulfate–hyaluronic acid; HFSC, hair follicle stem cell; VEGF, vascular endothelial growth factor.
