Figure 6. Histological evaluation of wound tissues. (A) Representative H&E and Masson staining images of wound tissues on day 7; (B) Density of neutrophils on day 7; (C-E) Quantitative analysis of (C) re-epithelialization length, (D) epidermal thickness, and (E) collagen content; (F) Representative H&E and Masson staining images of wound tissues on day 14. Data are expressed as mean ± standard deviation (n = 3 for day-7 histological analysis; n = 5 for day-14 histological analysis, ^*P < 0.05, ^**P < 0.01, ^***P < 0.001, ns: not significant). H&E: Hematoxylin and eosin; PCCD: polyacrylamide/sodium carboxymethyl cellulose/calcium chloride/dopamine; B-ESD: bilayer electrogenerative smart dressing.
