Abstract

Abstract: Objective To isolate and purify endometrial stromal cells from eutopic endometrium,ectopic tissue of patients with endometriosis (EMs) and normal endometrium. Detecting the expression of fibrosis-related protein in different tissues and corresponding stromal cells. Methods Fresh endometrial tissue was collected and modified EMs primary cell culture method was used. The cells were identified by immunohisto chemsistry. Western blotting was used to detect the consistency of fibrosis-related protein expression between the purified cells and the corresponding tissues. Results The primary isolation of stromal cells from endometrial tissue of EMs in situ was successful in 12 cases,the success rate was 100% (success index:cells adhered to the culture bottle and grew steadily). EMs ectopic tissue isolation and culture 12 successful 11 cases,the success rate of 91.7%. Eight cases of normal endometrial tissue were successfully isolated from 9 cases,with a success rate of 88.9%. There was no significant difference between human ectopic endometrial stromal cells (HEcESCs) and human eutopic endometrial stromal cells (HEuESCs) and normal human endometrial stromal cells (HEnESCs) under ordinary light microscope. But,Western blotting results showed that (P>0.05) the expression of fibrosis-related proteins in HEcESCs was significantly higher than that in HEuESCs and HEnESCs (P<0.01),and the expression of fibrosis-related proteins in stromal cells was consistent with there corresponding tissue levels. Conclusion The improved primary culture method of EMs cells can reduce the difficulty of EMs endometrial stromal cells culture,and maintain a high success rate of cell culture. The expression of fibrosis related protein in HEcESCs was significantly higher than that in HEuESCs and HEnESCs,that is mean,in patients with endometriosis,the ectopic lesions showed clear fibrosis at the tissue level.
