Osteocalcin levels in the conditioned media in MG63 cells silenced for integrins αl, α2, α5, and 31. (A) Osteocalcin levels in the conditioned media for integrin αl, (B) integrin α2, (C) integrin α5, and (D) integrin (β1, as well as MG63 cells were determined. Values presented are mean ± SEM of six independent cultures. Data were analyzed using ANOVA and statistical significance between groups was determined using Bonferroni’s modification of Student’s t-test. *p < 0.05 vs. TCPS; #p < 0.05 vs. MG63 cultures on matching substrates.
