Fig. 4From: Effect of Osteoking on the osteogenic and adipogenic differentiation potential of rat bone marrow mesenchymal stem cells in vitroEffect of different concentrations of Osteoking on osteogenic differentiation of rbMSCs. a Alizarin red staining of rat bone marrow mesenchymal stem cells (rbMSCs) cultured in osteoblast maturation medium with different concentrations of Osteoking after 20 days. X = dilution multiple of Osteoking. b Gene expression analysis for osterix (OSX), bone Sialoprotein II (BSPII) and Osteocalcin (OCN) in rbMSCs cultured in osteoblast maturation medium with different concentrations of Osteoking after 20 days by qRT-PCR. *p < 0.05, ***p < 0.001 vs. control; n = 5Back to article page
