PDGFRα/β expression in HBF versus LBF. a Real-time RT-PCR analysis of PDGFRα and PDGFRβ expression by HBF versus LBF clones, and b hBMSC-TERT^+Bone versus hBMSC-TERT^–Bone. Expression of each target gene was normalized to RG and presented as relative expression to RG. Data presented as mean (three different clones of each HBF and LBF clones) ± SEM of at least three independent experiments (*p ≤0.05, **p ≤0.01, ***p ≤0.005). HBF high bone forming, hBMSC human bone marrow stromal stem cells, LBF low bone forming, PDGFR platelet-derived growth factor receptor, RG reference genes
