Human umbilical mesenchymal stem cell and its adipogenic differentiation: Profiling by nuclear magnetic resonance spectroscopy

Figure 1 Human umbilical mesenchymal stem cells, adipogenic differentiation and red-o staining. A is the human mesenchymal stem cells at passage 4, the cells assumed a more spindle-shaped, fibroblastic morphology; B-D demonstrate the human umbilical mesenchymal stem cells (HUMSCs) after 2 wk adipogenic differentiation without and with the Red-O staining, respectively. The differentiated cells’ shape had transformed into an ovoid/round morphology and there were abundant lipid droplets presented in the cell periphery; E is the HUMSCs with Red-O staining without differentiation, no lipid body is visible.
