The FGFR2, PCNA, CDK1, CDK2, ALP, RUNX2, Osteopontin, Osteocalcin, and Caspase3 expression levels. A. Representative images of the western blots for PCNA, ALP, RUNX2, Osteopontin, Osteocalcin, and Caspase3 (pro- and cleaved-caspase3). B. Densitometric analyses of the PCNA, ALP, RUNX2, Osteopontin, and Osteocalcin proteins. C. Detection of the FGFR2, PCNA, CDK1, CDK2, ALP, RUNX2, Osteopontin and Osteocalcin mRNA were performed using RT-qPCR. The values were measured as the means ± SD, *P<0.05, **P<0.01, ***P<0.001.
