Figure 6.
Osteoblast attachment on the four different samples.
Notes: (A) Images of osteoblast attachment after 30, 60, and 120 minutes of incubation. The cells were stained with DAPI. n=6 at each time point. (B) Initial number of adherent cells measured by counting cells stained with DAPI. *P<0.05 and **P<0.01 compared with ST; #P<0.05 and ##P<0.01 compared with MT.
Abbreviations: MNT-Sr, micro/nano strontium-containing titanium surface; MT, micro titanium surface; NT-Sr, nano strontium-containing titanium surface; ST, smooth titanium surface.
