The human placenta in vitro releases luteinizing hormone-releasing factor (LRF) which is immunologically indistinguishable from hypothalamic LRF. The release of LRF by placental tissue increased during the 4 days of culture and exceeded the original tissue content more than 5-fold. These data suggest that the human placenta may synthesize an LRF molecule immunologically identical with hypothalamic LRF.
人胎盘在体外释放促黄体生成激素释放因子（LRF），其在免疫学上与下丘脑LRF无法区分。胎盘组织释放LRF的量在培养的4天内增加，且超过原始组织含量5倍以上。这些数据表明，人胎盘可能合成一种在免疫学上与下丘脑LRF相同的LRF分子。
