This study evaluated the mitogenic effects of peritoneal fluid from women with mild versus severe endometriosis on the proliferation of primary human endometrial stromal cells. Increasing concentrations of peritoneal fluid from women without endometriosis and with mild (stage I) or severe (stage IV) endometriosis were added to stromal cell cultures, and DNA synthesis was quantified by 3H-thymidine incorporation. Peritoneal fluid from mild endometriosis induced a statistically significant dose-dependent increase in stromal cell thymidine uptake (about 5.8–14.5-fold), whereas peritoneal fluid from severe endometriosis led to an average 51% inhibition of proliferation compared with non-endometriosis peritoneal fluid or nutrient medium with 2.5% calf serum. The paper’s findings are limited to an in vitro culture system using peritoneal fluid, without confirming how these effects translate in vivo. This paper is centrally about endometriosis — it tests how peritoneal fluid from mild versus severe endometriosis differentially affects endometrial stromal cell proliferation.

Abstract

The aim of this study was to evaluate and compare the mitogenic effect of peritoneal fluid (PF) from women with mild and severe endometriosis on the endometrial stromal cell proliferation. Increasing concentrations of PF from women with and without mild or severe endometriosis were added to primary endometrial stromal cell cultures and 3H-thymidine incorporation was used to assess DNA synthesis in these cultures. PF from women with mild endometriosis induced a statistically significant dose-dependent increase in stromal cell thymidine uptake ranged from 5.8 to 14.5 fold, whereas PF from women with severe endometriosis produced an average 51% inhibition of stromal cell proliferation of compared with cells exposed to non-endometriosis PF or exposed to nutrient medium supplemented with 2.5% calf serum alone. PF samples from patients with stage I endometriosis induced a statistically dose-dependent increase in stromal cell proliferation, whereas PF from patients with stage IV endometriosis caused a significant inhibition.
