Diabetic wound healing studies in vivo. a Images of wound healing with different treatment groups on days 0, 7, 14, 21; b Schematic diagram of wound healing in different treatment groups. The pink area meant the initial wound area and purple area represented the wound area at different time points; c The wound closure rates at different time points; d Quantification of wound area at day 21 (*p < 0.05 and **p < 0.01)
