Methods
Primary ESCs were prepared from 12 samples of ectopic endometrial tissue (6 peritoneal and 6 ovarian lesions), 18 samples of eutopic endometrial tissues (16 from women with ovarian and 2 from women with pelvic endometriomas) and 12 samples of normal endometrial tissue from women without endometriosis, after the tissues had been analyzed histologically. The growth, invasiveness and adhesion of ESCs were studied by the 5-bromo-2'-deoxyuridine cell proliferation assay and by the Matrigel invasion and adhesion assay. Additionally, the effects of NME1 on the activation or expression of related regulatory proteins were investigated by in-cell Western and flow cytometry assays. Main
