Molecular characterization of endometrial primary cultures To help characterize the isolated epithelial and fibroblast cells, we performed quantitative Rtpcr to determine the expression of many epithelial GSK923295 clinical trial and fibroblast markers. EC14 Ep cells and epithelial EC6 Ep showed higher expression of EpCAM, cytokeratin 8 and E cadherin, with minimal expression of vimentin and,SMA, The expression level shown was normalized with the level of GAPDH. In contrast, the four fibroblast cells separated from endometrial cancer tissues showed higher expression of vimentin and,SMA, with minimal expression of EpCAM, E cadherin and cytokeratin 8, These data suggested that we were successful in separating relatively natural epithelial cells with their fibroblast counterparts from the endometrial cancer tissues. Additionally, we also identified that both epithelial and fibroblast cells from EC tissues expressed varying quantities of estrogen and progesterone receptors, consistent with the statement that EC are hormone responsive cancers. We measured the mRNA expression of three generally produced proteins from the endometrium, progestagen Gene expression associated endometrial protein and matrix metalloproteinase 9 and 1 in these cells. As shown in Figure 3D F, PAEP were primarily expressed by fibroblasts, and better MMP1 expression was observed in comparison to that of MMP9 in both fibroblast and epithelial cells. Taken together, our data strongly suggested why these major epithelial and fibroblast tissues were preserving their in vivo phenotypes. Differential effects of endometrial fibroblast secretion on endometrial cancer cells It had been previously shown the secretions from normal endometrial fibroblast cells were growth inhibitory for the endometrial AGI-5198 clinical trial cancer cell line, Ishikawa cells, Consistently, conditioned media from normal endometrial fibroblast To HESC cell line inhibited the proliferation of ECC 1 and HEC 1A, in a dose-dependent fashion, At 2 gl, we noticed an important 51% and 69% growth inhibition in ECC 1,and HEC 1A, respectively. Similarly, primary endometrial cancer cells, EC6 Ep and EC14 Ep were also growth inhibited by To HESC conditioned media, To ascertain and compare the consequences of CAFs secretions on endometrial cancer cells, we collected conditioned media from 72 hours cultured fibroblast cells, and subsequently handled ECC 1 and HEC 1A human endometrial cancer cell lines for 72 hours. Interestingly, conditioned media from cancer associated fibroblasts activated a diverse effect.
