Metabolic activity determined by alamarBlue Assay of normal human dermal fibroblasts (NHDF) cultured in 3D Collagen/Chitosan based scaffolds enriched by SeNPs of different concentrations (0.5, 1.0, 5.0 μg/ml) or enriched by SeNPs of different concentrations (0.5, 1.0, 5.0 μg/ml) and by FGF2-STAB® of concentration 1 μg/ml for 1 day (a) and 3 days (b). Metabolic activity was assessed by alamarBlue. P-value below 0.05 (*) indicates significant differences between enriched scaffolds and the dedicated control scaffold (Collagen/Chitosan without SeNPs) (Mann–Whitney test with Bonferroni correction)
