Uptake of [³H]triolein by the fetal unit and maternal liver (inset) at different times after injection. Pregnant dams [18.5 days postconception (dpc)] were injected iv with Lyposyn II that had been radiolabeled with [³H]triolein. After 5, 20, 45, and 120 min, fetuses, placentas, and maternal livers were rapidly collected. Tissues were saponified, fatty acids were extracted, and amount of radiolabel was measured. Data are presented as means ± SE (n = 3 litters). Inset: percent radiolabel taken up by maternal liver. *Differences (P < 0.05) from 5-min time point.
