mRNA expression of BMP-2 in the proximal femur. (Original gels are presented in Supplementary Fig. 3). (A) Quantification of BMP-2 mRNA expression was carried out through PCR analysis. The PCR marker, labeled M, indicates size standards ranging from 250 bp at the bottom to 500 bp at the top. (B) The data are represented as expression ratios, which were standardized against β-actin gene expression and are displayed as the mean ± standard deviation (n = 6). #: P < 0.05 versus the PS group, *: P < 0.05 versus the MPSL group.
