Fig. 3. (a) Optical microscopic images of differentiated cells (104 cell per well) on the scaffolds (0.5 × 0.5 cm2) after 21 days. Tissue culture plate was used as the control. S was l-ascorbic acid (10 mM) and dexamethasone (1 mM). The magnification is 100. (b) The viability of the cells on the scaffolds up to 21 days obtained by MTT assay. (c) SEM images of the cells on PCL/βC4% scaffold after 14 days.
