a Immunostaining of IL-6 of granulation tissues in different groups. c Immunostaining of TNF-α of granulation tissues in different groups. e Masson’s trichrome staining for collagen in different groups. Scale bars are all 50 μm. In each panel, (i) is the control group, (ii) is the IOF group, (iii) is the IOF + CS + VEGF group. Statistical analysis of b IL-6, d TNF-α and f collagen deposition in different groups after 9 days of wound repair. NS not significant, 0.01 < *p < 0.05, **p < 0.01 (n = 4)
