摘　　要：目的　探讨甾体激素、黄体生成素释放激素 (LHRH)、人绒毛膜促性腺激素 (hCG)、促卵泡激素 (FSH)在子宫内膜间质细胞蜕膜化过程中的作用。方法　取 18例育龄期妇女的增殖期子宫内膜 ,行体外分离、培养其间质细胞 ,加入生理剂量的雌二醇 (E2 )、孕酮 (P)、睾酮 (T) ,以及LHRH、hCG、FSH ,在相差显微镜下观察细胞的形态学改变 ,采用放射免疫法测定培养液中泌乳素 (PRL)的含量。结果　E2 、P、T对子宫内膜间质细胞的生长及分化均有调节作用 ,PRL开始上升与多角形细胞出现的时间相一致 ,P、T对子宫内膜间质细胞分泌PRL起主要作用 (P <0 0 1) ,P与E2 、T有协同作用。LHRHhCG、FSH对子宫内膜间质细胞蜕膜化、分泌PRL均有促进作用 (P <0 0 1) ,以hCG的作用最强。结论　P、T、E2 在子宫内膜间质细胞生长分化过程中起重要作用 ,LHRH、hCG。Objective To investigate the roles of luteinizing hormone releasing hormone (LHRH), follicle stimulating hormone (FSH), human chorionic gonadotropin (hCG) and ovary steroids in regulation of human endometrial stroma cell (ESC) decidualization Methods Stroma cells derived from human endometrium during the proliferative phase were cultured in vitro and treated with physiological doses of estradiol (E 2), testosterone (T),progesterone(P) or LHRH, FSH and hCG Their morphologic changes and prolactin (PRL) production in the media were examined and compared Results Addition of E 2 or T or P stimulated ESC proliferation, resulting in increase of the saturation density The fibroblast morphologic changes to polygonal shape and began to express PRL simutaneously after treatment of P or T P in presence of E 2 or T significantly enhanced PRL production( P <0 01), suggesting a synergistic action between them in stimulating ESC decidualization LHRH, FSH or hCG also induced morphologic changes and PRL production by ESC in the presence of E 2+P Among them the impact of hCG is most remarkable, especially in this culture system Conclusions E 2, T and P play an important role in proliferation and differentiation of the ESC LHRH, FSH, hCG also directly exert an effect on ESC decidualization
