Multilineage differentiation identification of human mesenchymal stem cells. Morphology of human mesenchymal stem cells at the third passage (A) (100 T) and multilineage differentiation capacities of mouse mesenchymal stem cells, including adipogenic differentiation stained with Oil Red O (B) (200 T), osteogenic differentiation stained with Alizarin red (C) (200 T), and chondrogenic differentiation stained with Toluidine blue (D) (200 T), were observed by microscope.
