Hydrogel system promoted diabetic wound repair and regeneration in vivo. a Schematic diagram of diabetic wound and in situ hydrogel system photocuring. b Photographs of the wounds with different treatments on days 0 (before and after photocuring), 3, 7, 10 and 14. c Skin wound healing rate of the diabetic wound model at different time points. d Weight of the all-diabetic mice at different time points. e The overlaid images of the wound healed by different treatments on days 0 (red), 3 (yellow), 7 (green), 10 (blue) and 14 (purple). f H&E staining of the wound area on days 1, 3, 7, and 14 reflected the tissue-repair. (scale bar: 50 μm). g Masson’s trichrome staining on days 1, 3, 7, and 14 reflected collagen deposition (Scale bar: 50 μm)
