Photomicrographs of control and induced BM-MSCs and SM-MSCs stained with alizarin red (osteogenesis) and Oil Red O (adipogenesis). Osteogenically induced MSCs stained with alizarin red are positive for extracellular calcium consistent with osteogenesis. Adipogenically induced MSCs demonstrated positive Oil Red O staining of lipid droplets consistent with adipogenesis. (Bar = 100 μm)
