Proliferative activity of osteoblasts from sham and OVX groups on untreated and photofunctionalized titanium surfaces. 5-Bromo-2′ deoxyuridine (BrdU) incorporation into DNA during mitosis standardized by cell number. BrdU incorporation into DNA measured on day 5. Each value represents the mean ± standard deviation from triplicate experiments (n = 3). * p < 0.05, significant difference between untreated and photofunctionalized surfaces.
