Morphology of single cell-derived, clonally expanded UCB MSCs. The lineage-depleted mononuclear fraction was plated in culturing medium, culture expanded, and plated at a density of 30 cells/96-well plate. Single cell-derived clones were then culture expanded and maintained between 30% and 60% confluence. Original magnification, × 100. Scale bar indicates 100 μm.
