Morphological observations of the hUC-MSCs. Observation of cell morphology of the passage 3 hUC-MSCs in the DE, IE and NC groups. All cells exhibited the characteristic MSC fibroblast-like spindle shape with the DE group achieving 100% confluence at day 8 while the IE group with the least confluency even after day 10. The NC group achieved 100% confluence at day 10. All photo micrographs were taken using CKX41 Inverted Microscope (Olympus, Japan) with 100X magnification.
