Fig. 15From: Human umbilical cord-derived mesenchymal stromal cells ameliorate aging-associated skeletal muscle atrophy and dysfunction by modulating apoptosis and mitochondrial damage in SAMP10 miceMorphology of the umbilical cord-derived mesenchymal stem cells (UC-MSCs) in the early, middle, and late phases. A Representative phase-contrast micrographs showed that there were many small, raised cells with a fibroblast-like appearance in the early phase, and then more and more cells appeared to be irregular and gained flat morphology in the 6th and 8th passages.
