Mitochondrial activity in human dermal fibroblasts determined by an MTS assay in six time intervals (on days 1, 3, 5, 7, 10, and 14 after cell seeding) on nonmodified PLA membranes or on PLA membranes with a fibrin nanocoating (F).

Notes: Cells cultivated in the standard cell culture medium or in a medium supplemented with AA. The PSs were used as a control material. Arithmetic mean ± SD from 16 measurements made on four independent samples for each experimental group and time interval. ANOVA, Student–Newman–Keuls method, statistical significance (P≤0.05): *compared with a nonmodified PLA membrane in the standard cell culture medium or in the medium with AA, and AA compared with membranes in the standard cell culture medium.

Abbreviations: PLA, polylactide; AA, 2-phospho-l-ascorbic acid trisodium salt; PSs, polystyrene culture dishes; SD, standard deviation; ANOVA, analysis of variance; PLA F, fibrin nanocoating on PLA.
