Fig. 1From: Effects of melatonin-pretreated adipose-derived mesenchymal stem cells (MSC) in an animal model of spinal cord injuryThe morphology and density of ADSCs and MT-ADSCs. Undifferentiated ADSCs and undifferentiated MT-ADSCs display a flattened fibroblast-like morphology under phase-contrast microscopy. Within 4–5 days in culture medium, MT-ADSCs (80–90%) reached higher densities than ADSCs (40–50%); (Magnification: 20×)Back to article page
