Research of angiogenic potential of human multipotent mesenchymal stromal cells
Abstract
To study the angiogenic potential of cell cultures a new 3D model of using the VEGF-induced spheroids from umbilical cord multipotent mesenchymal stromal cells (UC MMSC) was elaborated. It was shown that in the process o f forming spheroids UC MMSC the number of early endothelial progenitor cells expressing CD34+, CD133+ increased as compared with 2D culture. The expression of markers of late endothelial progenitor cells (CD31+/vWF+/ F lk -1+/ VEGF+) was induced by VEGF. After transfer into Matrigel in spheroids the formation tubular like structures were discovered.
