Fig. 1From: Inositol pyrophosphates mediated the apoptosis induced by hypoxic injury in bone marrow-derived mesenchymal stem cells by autophagyCharacter of BM-MSCs. a BM-MSCs had fibroblast-like shapes. Oil Red O staining, Alizarin Red S staining, and Alcian blue staining detected Adipogenesis, osteogenesis, and chondrogenesis of BM-MSCs respectively (scale bar, 100 μm). b Results of flow cytometry demonstrate that BM-MSCs were negative for CD45, CD34, Vimentin, SMA, and c-kit and positive for CD90, CD29, CD44Back to article page
