Fig. 7. Viability and proliferation of NTC fibroblasts seeded with nanofibrous scaffolds determined by MTT assay after 2 and 6 days in standard culture conditions. Statistical significance: *p < 0.05; **p < 0.001 (comparison between two different samples during one time point); ####p < 0.0001 (comparison of the same sample between different time points).
