The expression of bone formation related markers. Analysis of serum OCN levels (A). The mRNA expression levels on femur were measured by qRT-PCR for bone COL-I (B), OCN (C), BMP-2 (D), RUNX2 (E) and OSX (F). Data were the means ± SD (n = 6 for each group). # P < 0.05 and ## P < 0.01, vs. the SHAM group. *P < 0.05 and **P < 0.01, vs. the DEX group.
