Collection Summary: | Placentomes were collected at necropsy from control ewes and ewes treated with cortisol (CORT: 1mg/kg/d from day 115 of pregnancy) at days 141-144 of gestation. CORT ewes received an intravenous infusion of cortisol (Solu-Cortef, hydrocortisone sodium succinate in sodium phosphate; Pfizer, New York, NY); control animals did not receive any treatment. Animals were sacrificed for collection of tissues at the first signs of labor, as evidenced by changes in uterine blood flow; placentomes were collected from sheep in early stages of labor at between 141-144 days and 142-144 days of gestation in the cortisol-treated and control groups, respectively. In this cohort of ewes, there were 7 control ewes, of which data were collected from placentomes of 7 live fetuses (including one set of twins); there was one lamb born, and that placenta was not collected. In this cohort there were 11 cortisol- treated ewes, from which we collected placentomes from 5 live fetuses. There was one live lamb born, and 5 stillborn lambs, from which placentas were not collected. Placentomes were classified as A-D placentomes, snap frozen in liquid nitrogen, and stored in -80C until metabolomic analysis. |
