NHDF metabolic activity represented in absorbance units in dependence on increasing SeNPs concentration for Collagen/Chitosan scaffolds after 3, 7 and 10 days of incubation a without FGF2-STAB® and b with 2 µg/ml of FGF2-STAB®. Data represent the mean ± SD of minimum 6 biologically independent experiments with technical triplicate each. P-value below 0.05 (*) are considered statistically significant (Kruskal–Wallis test H)
