Multi-differentiation potential of the BMSCs cultured with various differentiation media for 3 weeks. a, b The cells were cultured with basic medium for 3 weeks and stained with oil red O. c, d The cells were cultured with adipogenic differentiation medium for 3 weeks and stained with oil red O. e, f The cells were cultured with basic medium for 3 weeks and stained with alizarin red S. g, h The cells were cultured with osteogenic differentiation medium for 3 weeks and stained with alizarin red S. i, j The cells were cultured with basic medium for 3 weeks and stained with Safranin O. k, l The cells were cultured with chondrogenic differentiation medium for 3 weeks and stained with Safranin O. Black bars 100 μm; white bars 20 μm; blue bars 200 μm; pink bars 40 μm
