{"paper_id":"5c97c9ba-32ce-488e-bdea-7ae48ee9e482","body_text":"Cell cultures isolated from endometriosis lesions by enzymatic dissociation consisted of fibroblast-like cells expressing CD90, CD73, and CD105; cell viability in these cultures was >90%, but this parameter decreased by passage 3. Zero passage cultures contained 10-25% epithelial cells expressing cytokeratin-7, but by passage 2, the cultures became more homogeneous and epithelial cells disappeared. The proportion of proliferating cells and population doubling level increased from passage 1 to passage 3. The cultures from the endometrium were induced to adipogenic and osteogenic differentiation in vitro. The cultures derived from ectopic endometrium have properties of multipotent mesenchymal stromal cells that exhibited in vitro similarities and differences from cell cultures from eutopic endometrium, which allows using this cell model for the search and testing of new drugs and technologies aimed at suppression of the growth and spread of endometriosis lesions.\nSimilar content being viewed by others\nReferences\nAdamyan LV, Sonova MM, Tikhonova ES, Zimina EV, Antonova SO.
