Cell migration after exposure to the extracts of biomaterials: (a) migration of human skin fibroblasts (BJ cell line) and (b) migration of human epidermal keratinocytes (HEK001 cell line) (control–cells maintained in the presence of polystyrene extract); * statistically significant results between indicated groups, n = 3, p < 0.05, one-way ANOVA followed by Tukey’s test (Mat1: curdlan/agarose biomaterial, Mat2: curdlan/chitosan biomaterial, C–vitamin C, H–hydrocortisone, C/H–mixture of vitamin C and hydrocortisone, T = 0 h–wound surface just after scratching, T = 24 h–wound surface 24 h after scratching).
