1,25(OH)2D3 Mitigates Oxidative Stress-Induced Damage to Nucleus Pulposus-Derived Mesenchymal Stem Cells through PI3K/Akt Pathway
Figure 1
Identification of nucleus pulposus-derived mesenchymal stem cells (NPMSCs). (a) NPMSCs present with a long spindle shape and grow in a flower formation ( μm). (b) NPMSCs exhibit a low fluorescence expression of the hematopoietic stem cell surface markers CD34 and CD45, but a high fluorescence expression of the MSC surface markers CD73, CD90, and CD105; (c) NPMSCs are positive for Alizarin red, Oil Red O, and Alcian blue staining after multilineage differentiation ( μm; μm).
