Histological analysis of osteogenesis and angiogenesis after coatings implantation. A HE staining during bone formation. S denotes the coating implantation site, NBT denotes the new bone trabecula, NMC denotes the new bone marrow cavity and the black arrow indicates the new blood vessels. B The numbers of neovascularization. C The areas of neovascularization. D The expression of COL-1 on the 30th day after coatings implantation. E The percentage of area of COL-1 signals. F The expression of CD31 on the 30th day after coatings implantation. G The percentage of area of CD31 signals. Microscope magnification was ×200. Scale bar = 100 μm. *P < 0.05, **P < 0.01, ***P < 0.001 and ****P < 0.0001 were obtained by comparison with uncoated Ti
