Incubation of 1 x 10(6) bovine binucleate trophoblastic cells (BTC) for 6 h with 0.20 and 0.30 microM-Ca2+ ionophore A23187 increased (P less than 0.01) net progesterone production 49% and 111%, respectively, compared to BTC without A23187. Addition of 3 mM-8-bromo-cAMP with A23187 had no effect on the response. Trifluoperazine (40 microM), an inhibitor of(More)
A procedure for preparing highly enriched suspensions of bovine binucleate trophoblastic cells was developed and data showing that these cells produce progesterone, prostacyclin (PGI2), and prostaglandin E2 (PGE2) were obtained. Approximately 200 X 10(6) enzymatically dissociated cells from bovine cotyledons were applied to the surface of a density gradient(More)
Effects of short-term fasting on the insulin and glucose responses to injected glucose were determined in obese (n = 6) and lean (n = 6) Dorset ewes that were fed a maintenance level of energy intake. Sheep were assigned by Latin-square design to be fasted for 0 (fed), 12 or 24 h before glucose (350 mg/kg) was injected via jugular cannula at 2000 h with at(More)
