| Abstract: | A method was elaborated to evaluate the biological activity of expression products of gene in the plasmid vectors, which are crucial for the synthesis of growth factor of blood vessels. It was proven as possible that the chrioallantonic membrane (CAM) of chicken's embryos could be transfected by recombinant plasmids containing both the reporter and target genes. The efficiency of CAM transfection was assessed by a plasmid carrying the reporter gene of green fluorescent protein (GFP). Finally, it was demonstrated that, at an infiltration of the recombinant plasmid containing the human angiogenine gene, its expression products induce the neovascularization in the CAM cells of chicken's embryos and stimulate an accretion in vessels of the 1st, 2nd and 3d orders. |
