Osteoblast phenotypic expression in mono- layer culture depends on surface microtopography. Here we tested the hypothesis that mineralized bone nodule formation in response to osteotropic agents such as bone morphogenetic protein-2(BMP-2 ) and dexameth- asone is also influenced by surface microtopography. Fetal rat calvarial (FRC) cells were cultured on Ti im- plant materials (PT (pretreated), Ra = 0.6 lm; SLA (course grit blasted and acid etched), Ra = 4.0 lm; TPS (Ti plasma sprayed), Ra = 5.2 lm) in the presence of either BMP-2(2 0 ng/ml) or 10 )8 M dexamethasone (Dex). At 14 days post-confluence, a homogenous layer of cells covered the surfaces, and stacks of...
