Estradiol did not affect endometriotic cell growth, but progesterone inhibited it, an effect reversed by RU486, while EGF and other growth factors increased DNA synthesis.

Researchers established a primary cell culture of endometriotic cells to investigate how various hormones and growth factors regulate cellular proliferation. The study found that while estradiol had no effect on DNA synthesis, progesterone significantly inhibited it, an action that was completely reversed by the antiprogesterone RU486. Additionally, epidermal growth factor and other growth factors like fibroblast growth factor and insulin-like growth factor modestly increased DNA synthesis in these cultures. This paper is centrally about endometriosis — specifically examining the hormonal regulation of endometriotic cell growth in vitro.

Abstract

A primary cell culture of endometriotic cells was established to examine the hormonal regulation of endometriosis. The addition of estradiol had no effect on the DNA synthesis of cultured endometriotic cells. Progesterone at 10(-7) M caused a significant reduction in the amount of the DNA synthesis. An inhibitory effect of progesterone was completely eliminated by the concomitant addition of RU486, an antiprogesterone. The addition of epidermal growth factor (EGF) at 1 ng/ml significantly increased the DNA synthesis. Other growth factors, such as fibroblast growth factor and insulin-like growth factor also produced a modest but significant increase in DNA synthesis. These results seem to provide clues for clarifying the pathophysiology of endometriosis.

Summary A primary cell culture of endometriotic cells was established to examine the hormonal regulation of endometriosis. The addition of estradiol had no effect on the DNA synthesis of cultured endometriotic cells. Progesterone at 10−7 M caused a significant reduction in the amount of the DNA synthesis. An inhibitory effect of progesterone was completely eliminated by the concomitant addition of RU486, an antiprogesterone. The addition of epidermal growth factor (EGF) at 1 ng/ml significantly increased the DNA synthesis. Other growth factors, such as fibroblast growth factor and insulin-like growth factor also produced a modest but significant increase in DNA synthesis. These results seem to provide clues for clarifying the pathophysiology of endometriosis.
