Figure 5
The fluorescent pictures of endothelial cells adhered to the surfaces of different samples (a). CCK-8 values (b), VEGF (c), and NO (d) activities of endothelial cells grown on the different sample surfaces for 1 and 3 days, respectively. Statistical significance of is indicated by as compared with the Ti group and by as compared with the Ti and TNT groups.
