Isolation and characterization of MSCs. a The morphology of MSCs. b After induction, the cells possessed the typical phenotypes of osteocytes (stained with Alizarin Red S). c After induction, the cells possessed the typical phenotypes of adipocytes (stained with Oil Red O). d After induction, the cells possessed the typical phenotypes of chondrogenesis (stained with Alcian blue staining). e Differentiated cells express the MSCs markers, CD29, CD40, and CD90, but do not express the hematopoietic or endothelial markers, CD11b, CD34, and CD45
