Figure 2. Adenovirus-mediated bFGF and BMP2 gene expression levels and protein concentrations in the supernatant.

(A)The BMP2 and bFGF mRNA expression levels in transfected BMSCs at 72 h were analyzed by RT-PCR. The protein concentrations of BMP2 (B) and bFGF (C) were determined by ELISA. The bar represents the mean ± SEM of three independent experiments. *P < 0.05 and **P < 0.01 compared to the control group.
