Hydrogels accelerating diabetic infection wound repair. a H&E staining of wound tissues at early phase. b immunofluorescent staining analysis of the microvessel density (CD31) during the proliferation phase (n = 6). c Collagen deposition during the remolding phase (n = 6). Bar graphs represent mean + SD. N.S means no significant difference between these groups. *p < 0.05; **p < 0.01; ***p < 0.001
