Surface topography influences cell adhesion. (A,B) The relative mRNA levels of integrin α2 and vinculin in cell cultured on different titanium surfaces for 6 and 24 h. Statistical significance was determined by one-way ANOVA. Error bars represent SD (n = 3). *P < 0.05. **P < 0.01. ***P < 0.005. (C,D) Western blot analysis of integrin α2, vinculin, FAK and p-FAK in cell cultured on different titanium surfaces for 6 (C) and 24 h (D). Cells were cultured on different materials as indicated above.
