Fig. 1From: Mechanisms underlying the role of endoplasmic reticulum stress in the placental injury and fetal growth restriction in an ovine gestation modelInfluence of BPA on the placental efficiency and the levels of E2 and P4 as well as the weights of placentas and fetuses in the type A COT tissues of Hu ewes on d 130 of gestation. A Total weights of the placenta and type A placentomes. B Weight of the fetuses. C Placental efficiency. D The levels of E2 and P4. Data are presented as means ± SEM, n = 8. Means with no common letter are different (P < 0.05). BPA group, pregnant Hu ewes receiving Bisphenol A (5 mg/kg/d mixed sufficiently into corn oil) through subcutaneous injection; CON group, pregnant Hu ewes receiving corn oil only; COT, cotyledonary; E2, estradiol; P4, progesteroneBack to article page
