23 Jul Method of preparing containing endothelium ancestor cell preparation utilizing umbilical or placenta and uses thereof
Abstract
The invention discloses a method which adopts umbilical cord or placenta to prepare a preparation containing endothelial progenitor cells and an application of the preparation, mainly relating to a novel source of an endothelial progenitor cell preparation and a preparation method of the endothelial progenitor cell preparation. The stem cell preparation adopts the placenta or the umbilical cord as the source of the cells; mesenchymal stem cells are firstly separated and amplified; and then VEGF is added to induce the mesenchymal stem cells to be differentiated into the endothelial progenitor cells. The endothelial progenitor cell preparation prepared according to the invention contains a large number of endothelial progenitor cells. The preparation can be applied to clinical treatment and tissue engineering, etc. The raw material sources of the preparation are rich; the success rate of the separation and the yield are high; and the proliferation ability of the cells is strong.
