Surface Immobilization of TiO2 Nanotubes with Bone Morphogenetic Protein-2 Synergistically Enhances Initial Preosteoblast Adhesion and Osseointegration

Figure 5

Osteoblast adhesion measured by counting cells stained with DAPI under a fluorescence microscope after 4h of incubation. (a): representative images of Ti, TNT, hBMP-2/Ti, and hBMP-2/TNT samples. (b): summary of adherent cell numbers on different surfaces. Values are mean ± SD, n=3; , #, and @ indicate p < 0.05 compared with Ti, TNT, and hBMP-2/Ti, respectively. Scale bar, 100 μm.
