Fig. 3From: Polydopamine (PDA) coatings with endothelial vascular growth factor (VEGF) immobilization inhibiting neointimal formation post zinc (zn) wire implantation in rat aortasThe adhesion and proliferation of HUVECs on different Zn surfaces. (a) The adhesion and spreading of HUVECs on different Zn surfaces. (b) The CCK-8 results of HUVECs adhered on different Zn surfaces 24 h after cell seeding. (c) Quantification of cell covered areas of HUVECs cultured on different Zn surfaces for 7 days. (d) The proliferation of HUVECs cultured on different Zn surfaces for 7 days. The CCK-8 results of HUVECs adhered on different Zn surfaces for 3 days (e), 5 days (f), and 7 days (g). * indicates p < 0.05, compared between two groups. ** indicates p < 0.01, compared between two groupsBack to article page
