Growth and development of the ovine conceptus.
This study was designed to characterize development of the ovine conceptus throughout gestation to establish the temporal relationships in metabolites, electrolytes, fluid volumes within the placenta, and hormonal changes with fetal growth. Length and weight of placentae, weight of cotyledons, and uterine weight increased between d 25 and 80 of gestation in advance of increases in fetal growth ...
متن کاملDevelopmental regulation of prostacyclin synthase and prostacyclin receptors in the ovine uterus and conceptus during the peri-implantation period.
This study documents the expression of prostacyclin (PGI2) synthase (PTGIS) and PGI2 receptors in the trophoblast and uterus of the ewe at the time of maternal recognition of pregnancy (i.e. days 7, 9, 12, 14 and 17). The membrane receptor for PGI2 (PTGIR) and the nuclear receptors, i.e. peroxisome proliferator-activated receptors (PPAR) and their heterodimer partners the retinoid X receptors (...
متن کاملExtracellular Vesicles in Luminal Fluid of the Ovine Uterus
Microvesicles and exosomes are nanoparticles released from cells and can contain small RNAs, mRNA and proteins that affect cells at distant sites. In sheep, endogenous beta retroviruses (enJSRVs) are expressed in the endometrial epithelia of the uterus and can be transferred to the conceptus trophectoderm. One potential mechanism of enJSRVs transfer from the uterus to the conceptus is via exoso...
متن کاملPrenatal development of ovine fetus.
From 39 gravid ovine genitalia in various stages of gestation, collected from a local slaughter house in Srinagar city, 37 and 4 fetuses were obtained from single and twin pregnancies, respectively. The genitalia collected were divided into four stages of gestation as: Stage- I (30-60 days); Stage-II (61-90 days); Stage-III (91-120 days); and Stage-IV (120 days to term).Various measurements of ...
متن کاملCathepsins in the ovine uterus: regulation by pregnancy, progesterone, and interferon tau.
Cathepsins (CTS) are peptidases that have biological roles in degrading extracellular matrix, catabolism of intracellular proteins, and processing of prohormones. Expression of CTSB, CTSD, CTSH, CTSK, CTSL, CTSS, and CTSZ genes was detected in the endometria of cyclic and early pregnant ewes with distinct temporal and spatial expression patterns. In the d 18 and 20 conceptus, expression of CTSB...
