Fig. 8 — Analysis of wound healing process. (A) H&E stain image of regenerated skin tissue, 100 $μ m$ on the scale (yellow dotted line denoted epithelial-dermal boundary, purple arrows denoted capillaries, and green arrows denoted hair follicles), scale bar: 100 $μ m$ . (B) Capillary densities density of granulation tissue under different treatments, data were normalised against the results of the gauze group at day 7, and the data of the gauze group was defined as 100%. (C) Epithelial thickness of granulation tissues following different treatments at day 14. (D) Hair follicle density of regenerated skin tissues in each group on day 14, data were normalised against the normal skin tissues of diabetic rats at day 14, and the data of the normal skin tissues was defined as 100%. Note: Hydrogel Ⅱ: the CBP/GMs hydrogel; Hydrogel Ⅲ: the CBP/GMs@INS hydrogel; Hydrogel Ⅳ: the CBP/GMs@Cel&INS hydrogel.
