<p>The invention relates to biotechnology, in particular to producing endothelial cells from human embryonic stem cells and to the use thereof. The inventive method for producing endothelial cells from human embryonic stem cells involves differentiating human embryonic stem cells on a substrate and in a synthetic medium that provide targeted direct differentiation of hESCs into endothelial cells based on a mixture of DMEM/F12 and a KO serum substitute having VEGF, SCF, BMP4, bFGF and TGFbeta growth factors and taken in effective quantities, wherein TGFbeta is introduced on 3rd-6th day of differentiation. A differentiation medium based on the mixture of DMEM/F12 with fetal bovine serum having VEGF, SCF and bFGF growth factors can be also used. The separation is carried out on 3rd-9th day according to an immunological selection method using markers specific for endothelial cells and, afterwards, the thus produced endothelial cells are cultivated in the abovementioned medium at the plating density of not less than 50,000 cells per cm 2 .</p> |
