Effect of PCL, P/nHA and, P/nHAEA nanofibrous scaffolds on DPSCs osteogenic differentiation: (a) Representative images of scaffolds stained with alizarin red dye at the 14 days. Scaffolds without cells stained with alizarin red for background removal (blank) (b) A bar chart demonstrating quantitative results of differentiated DPSCs stained with alizarin red S after 14 days of culture. *p < 0.05, **p < 0.01, ***p < 0.001 for each group compared to the control group; , differences between groups; ctrl, Control (without scaffold); ns, nonsignificant
