Prostaglandin E2 secretion by day-6 to day-9 equine embryos.
Prostaglandin E2 (PGE2) secreted by Day-6, Day-7, Day-8 and Day-9 equine embryos (ovulation = Day 0) during in vitro incubation was measured by radioimmunoassay. Embryonic PGE2 secretion (ng/embryo/24 hr) was detectable on Day 6 (0.27 +/- 0.39), tended to increase (P less than 0.1) on Day 7 (0.57 +/- 0.88), and increased significantly (P less than 0.05) on Day 8 (2.23 +/- 0.86) and Day 9 (4.13 +/- 0.71). Embryo diameter at the start of the incubation period was linearly correlated (P less than 0.01) to embryonic PGE2 secretion.
