Expression of mRNA for ITGA1, ITGA5, ITGAV, and ITGB3. Human MG63 osteoblast-like cells were harvested 12 hours after confluence on TCPS. Expression of mRNA for ITGA1, ITGA5, ITGAV, and ITGB3 were measured by real-time quantitative PCR of cells cultured on TCPS, PEEK, smooth titanium alloy (sTiAlV), or rough titanium alloy (rTiAlV). Expression is normalized to GAPDH.
