Fig. 7From: In situ forming ROS-scavenging hybrid hydrogel loaded with polydopamine-modified fullerene nanocomposites for promoting skin wound healingHistological analysis of the wound healing effect. A H&E staining of the skin wound sections by ×10 magnification on day 7 and day 14 after treatment. Red arrow: blood vessels; green arrow: inflammatory cells. B Masson’s trichrome staining of the wound tissues on day 14 post-treatment. C Quantification of re-epidermis thickness on day 14 post-treatment. D Quantitative analysis of collagen content (%) after 7 and 14 days of treatment. *P < 0.05, **P < 0.01, ***P < 0.001 and ****P < 0.0001Back to article page
