摘要
The results of injecting of autologic mesenchymal stem cells of bone marrow origin (AMSCBMO), transfected by the GFP gene, into the scar of rat uterine horns were studied by methods of light microscopy. After the introduction of AMSCBMO into the formed scar on the right (2 months after the ligation) large groups of blood vessels with cellular elements inside were present;groups like that were not found in the opposite side. Studying unstained sections under reflected ultraviolet light the sufficient bright luminescence in the endothelium and the external membrane of scar vessels was found in uterine horn only on the side of introduction of AMSCBMO. It was concluded that after the introduction of AMSCBMO into the scar tissue they form blood vessels by differentiation into endotheliocytes and pericytes. GFP gene expression not only in endothelium of vessels, but also in their external membrane indicates that differentiation of AMSCMBO is possible in endothelial and in pericytal directions.
