Trilineage differentiation of rbSF-MSCs characterized by qRT-PCR analysis. a, d Induced rbSF-MSCs had much higher levels of the osteogenic marker gene (Runx2 and Osteocalcin) than control cells. b, e Induced rbSF-MSCs had up-regulatd PPARγ and LPL compared with control cells. c, f Chondrogenic differentiation markers (Col2A1, Sox9) were significantly increased after induction compared to the control. Gene expression was normalized to GAPDH, and obtained from at least three independent experiments. (****P < 0.0001)
