Luteinizing hormone-releasing factor (LRF) has been found to be produced by the placenta. In the present study, the localization of this releasing factor was delineated by the use of an immunofluorescnece technique. Intense fluorescence was localized in the cytotrophoblast, along the outer surface layer of the syncytiotrophoblast, and in the villous stroma. The cytoplasm of the syncytiotrophoblast did not exhibit any fluorescence. It may be speculated that placental LRF plays a role in regulating the production of human chorionic gonadotropin.
已发现胎盘可产生促黄体生成素释放因子（LRF）。在本研究中，运用免疫荧光技术描绘了这种释放因子的定位。强烈荧光定位于细胞滋养层、合体滋养层外表面层以及绒毛间质。合体滋养层的细胞质未显示任何荧光。可以推测，胎盘LRF在调节人绒毛膜促性腺激素的产生中发挥作用。
