Regulatory effects of mifepristone and progesterone on the secretion of interleukin-6 by cultured eutopic and ectopic endometrial cells / 中华妇产科杂志

ABSTRACT

Objective To investigate the regulatory effects of mifepristone and progesterone on the secretion of interleukin 6 (IL 6) by endometrial and endometriosis cells in vitro. Methods Primary cultures of eutopic and ectopic endometrial cells from 9 cases of endometriosis were exposed to mifepristone (10 -6 mol/L, 10 -4 mol/L) and progesterone (1?10 -7 mol/L, 1?10 -5 mol/L) respectively. IL 6 secretion was analyzed in the culture medium by enzyme linked immunosorbent assay (ELISA). Results Mifepristone inhibited the IL 6 secretion of ectopic endometrial cells, with the concentrations of IL 6 was (1 914 33?799 28) ?g/L in the 1?10 -6 mol/L group ( P 0 05). Conclusion The inhibitory effects on the secretion of IL 6 by ectopic and (or) eutopic endometrium may provide one of the cellular therapeutic mechanisms of mifepristone and progesterone on endometriosis.
