Abstract:

BACKGROUND: Stem cells are induced to differentiate into endothelial-like cells that can be used for the treatment of diabetic lower extremity vascular disease. However, it is unclear whether these endothelial-like cells can completely replace endothelial cells to improve vascular disease and what are the differences between endothelial-like cells and endothelial cells.
OBJECTIVE: To explore the differences and similarities between endothelial-like cells and human umbilical vein endothelial cells in the aspects of morphology, function, and viability.
METHODS: Umbilical cord mesenchymal stem cells and umbilical vein endothelial cells were isolated, cultured and identified using flow cytometry and immunohistochemical method. Isolated umbilical cord mesenchymal stem cells were induced in DMEM-LG/F12 containing 10 µg/L vascular endothelial growth factor, 10 µg/L basic 
fibroblast growth factor and 2% fetal bovine serum to differentiate into endothelial-like cells followed by immunohistochemical identification. To compare endothelial-like cells with human umbilical vein endothelial cells, cell migration detection, active substance measurement and three-dimensional angiogenesis test were performed.
RESULTS AND CONCLUSION: Isolated umbilical cord mesenchymal stem cells strongly expressed the surface markers of mesenchymal stem cells, and human umbilical vein endothelial cells strongly expressed CD31 and VWF. After induction, the umbilical cord mesenchymal stem cells were identified to highly express CD31 and VWF. Through cell migration, active substance and three-dimensional angiogenesis tests, endothelial-like cells were similar to endothelial cells in the function and activity, and superior to endothelial cells.
