Characterization by multi-differentiation potential in human mesenchymal stem cells (hMSCs). hMSCs were differentiated into adipocytes, osteocytes, and chondrocytes. (A) Adipogenesis was confirmed by the presence of lipid droplets stained with Oil Red O. (B) Osteogenesis was confirmed with positive Von Kossa staining of osteoblast calcium deposits. (C) Chondrogenesis was indicated by the staining of collagen fibers with alcian blue.
