Umbilical cord mesenchymal stem cells protect thymus structure and function in aged C57 mice by downregulating aging-related genes and upregulating autophagy- and anti-oxidative stress-related genes
Figure 4. Cell growth morphology (100×). Note: (A) shows the first day of primary culture, as the cells migrate from the umbilical cord tissue. (B) shows the sixth day of primary culture, and the cells that grew were observed around the umbilical cord tissue. (C) is a cell from the P3 generation.
