Abstract
There is provided a simplified and inexpensive method for the in-vitro identification, isolation and culture of human vasculogenic progenitor cells. The method and the progenitor cells isolated thereby can be used for in-vitro vascular engineering, treatment of congenital and acquired vascular and hematological abnormalities, for evaluation and development of drugs affecting vasculo- and angiogenic processes, and for further investigation into tissue differentiation and development.
Claims3
A method of preparing vasculogenic progenitor cells from undifferentiated human or primate embryonic stem (ES) cells, the method comprising:
- (a) culturing individual undifferentiated human or primate ES cells under conditions which prevent cell aggregation and inducing differentiation of the undifferentiated human or primate ES cells into vasculogenic progenitor cells, thereby obtaining a mixed population of cells which comprises the vasculogenic progenitor cells;
- and
- (b) isolating cells smaller than 50 μm from said mixed population of cells, said cells smaller than 50 μm being vasculogenic progenitor cells.
