The cells from eutopic and ectopic endometrial tissues were primarily cultured in vitro.The morphologic features and function secretory markers of epithelial and stromal cells from both tissues were compared.The results revealed that with respect to the staining patterns for cytokeratins,vimentin and PRL,cultured cells from both tissues had similar properties.Cytokeratins were located in epithelial cells,and vimentin and PRL in stromal cells,while the CA125 and PRL were separately secreted in similar concen...
