Abstract:
In order to obtain models of gliomas of varying degrees of malignancy, we performed morphological and molecular genetic study of a tissue strain of glioma 10-17-2 (Astrid-17) obtained by intracranial passaging of tumor fragments of chemically induced rat brain tumor, and a cell strain isolated from it. More or less pronounced changes in the expression levels of Mki67, Trp53, Vegfa, and Gfap genes in the tissue and cell strain of glioma 10-17-2 (Astrid-17) compared with intact brain tissue were shown. The tissue model of glioma 10-17-2 (Astrid-17) according to the studied characteristics shows features of grade 3-4 astrocytoma and the cellular model - grade 2-3 astrocytoma.
