Multilineage differentiation identification of MSCs. The morphology of MSCs at the third passage (a × 100) and multilineage differentiation capacities of MSCs, including adipogenic differentiation stained with oil red-O (b × 200), osteogenic differentiation stained with alizarin red (c × 200), and chondrogenic differentiation stained with toluidine blue (d × 200), were observed with a microscope
