Fig. 2From: Effect of Osteoking on the osteogenic and adipogenic differentiation potential of rat bone marrow mesenchymal stem cells in vitroEvaluation of cytotoxicity of different concentrations of Osteoking on rat bone marrow mesenchymal stem cells. a Cell morphology after culturing with different concentrations of Osteoking for 4 days in bright light. X = dilution multiple of Osteoking. b Cell viability of rat bone marrow mesenchymal stem cells (rbMSCs) treated with different concentrations of Osteoking after 4 days by CCK-8 assay. **p < 0.01, ***p < 0.001 vs. control; n = 5Back to article page
