Effect of human Wharton's Jelly or adipose derived mesenchymal stem cells culture supernatant on endothelial cells angiogenesis

To compare the curative effect of mesenchymal stem cells derived from human Wharton's Jelly(WJ-MSC) or adipose(AD-MSC) culture supernatant on endothelial cells angiogenesis. WJ-MSC and AD-MSC were isolated, identified, and the culture supernatant of stem cells was collected.The WJ-MSC or AD-MSC supernatant co-cultured with the endothelial cells. The expression levels of pro-angiogenic and anti-angiogenic genes of endothelial cells were assessed using qRT-PCR analysis, and the effects of stem cell culture supernatant on angiogenesis were evaluated by performing a tube formation assay in vitro. After adding WJ-MSC and AD-MSC culture supernatant, the expression levels of pro-angiogenic genes in endothelial cells were upregulated, and the expression levels of anti-angiogenic genes were downregulated significantly in both experimental groups compared to the control group ( 0.01), and tube formation of endothelial cells was also significantly increased in both experimental groups as determined by the increase of th
