Abstract
Metabolically active tissues from second trimester human fetuses were examined for their ability to synthesize the placental hormones chorionic gonadotropin and chorionic somatomammotropin. During short-term incubation studies both placenta and fetal kidney were found to synthesize and secrete the beta-subunit of chorionic gonadotropin, whereas its synthesis was not observed in fetal liver, lung or muscle. In addition, chorionic somatomammotropin synthesis and secretion was demonstrated with placental tissue but could not be detected in any of the fetal tissues examined. These observations constitute the first evidence that the genome of a fetal tissue directs the synthesis of what is considered a placental hormone.
