| pubmed-article:1797131 | pubmed:abstractText | Homogenates of human term umbilical cord were incubated with 7n-3H-pregnenolone. Using a reverse-isotope dilution technique, 3H-progesterone was isolated and characterized. The extent of enzymic conversion ranged from 2.5 to 55.4%. The results indicate that the cord can be a source of progesterone during human pregnancy. | lld:pubmed |
