Comparison of osteogenesis-specific genes of primary osteoblasts and bone marrow stem cells (BMSCs) in the control, HA, BCP, and β-TCP groups in vitro. A, B mRNA expression of osteocalcin (Ocn), bone sialoprotein (Bsp), alpha-1 type I collagen (Col1a1), and runt-related transcription factor 2 (Runx2) by primary osteoblasts (A) and BMSCs (B) in the control, HA, BCP, and β-TCP groups on days 7 and 14. All data points are presented as the mean ± standard deviation (n = 3). *, # indicates P < 0.05; **, ## indicates P < 0.01; ***, ### indicates P < 0.001
