Gene expression quantification of osteoblastic markers by Real-Time PCR in total bone samples. ALPL, BMP2, COL1A1, BGLAP, and IGF2 gene expression was quantified in osteoporotic (OP) samples (n = 5) and compared to osteoarthritic (control) samples (n = 6). 18S was used as endogenous control. Results are expressed as mean and standard error
