<p>Bone morphogenetic protein-2 (BMP-2), runt-related transcription factor 2 (Runx2), bone sialoprotein (BSP), type I collagen (Col1), osteocalcin (OC), osterix (Osx), and osteopontin (OP) mRNA expression were analyzed. The experiment was performed in triplicate for each sample. Differences among the groups were evaluated by one-way analysis of variance (ANOVA; <i>p</i><0.05). Except for OP, there were no significant differences in expression levels among the groups.</p
