Figure 4. Effect of platelet-derived growth factor (PDGF)-BB and bone morphogenic protein 2 (BMP-2) transfection of rBMSCs on adipogenic differentiation. A, Oil red O staining for rat bone marrow mesenchymal stem cells (rBMSCs) in Sham, osteoporosis (OP), and PDGF-BB+BMP-2 groups (scale bar: 100 μm). B, qRT-PCR detection of adipogenic-related gene PPARγ in Sham, OP, and PDGF-BB+BMP2 groups. C, Western blot detection of adipogenic-related protein PPARγ in Sham, OP, and PDGF-BB+BMP-2 groups. Data are reported as means±SD. *P<0.05, **P<0.001 vs Sham group, #P<0.05 vs OP group (ANOVA).
