Figure 6.
Cell viability: (a) representative images of live (green) and dead (red) cells encapsulated in the scaffolds at a cell density of 6.0 × 106 cells/mL and cultured in undifferentiated (CTRL) and differentiated (TENO) medium after 1, 3, 7 and 14 days of cell culture (10× magnification; scale bar 10µm: N = 3); (b) cell viability of encapsulated ASCs at 1, 3, 7 and 14 days of cell culture (N = 3). Data were expressed as average ± standard deviation of arbitrary fluorescence units (AFU). Level of significance: ** p < 0.01, * p < 0.05.
