(a–d) The distribution of osteoblasts on different scaffolds. The cell density on the FTA scaffold (a–c) was superior to the CTA scaffold (d). Blue, nuclei staining with Hoechst 33258; green, RGD-FITC coated on the surface of Ti6Al4V alloy (bar = 50 μm). (e) Quantitative analysis of cell number in different groups (; ).
