Placental growth factor (PlGF) is a protein that in humans is encoded by the PGF gene. [5] [6] Placental growth factor (PGF) is a member of the VEGF (vascular endothelial growth factor) sub-family - a key molecule in angiogenesis and vasculogenesis, in particular during embryogenesis. The main source of PGF during pregnancy is the placental ...
Porcine. All three previously mentioned types of retinol-binding proteins (RBP, CRBP, CRABP) have been identified within the porcine placenta during pregnancy via immunohistochemistry. [14] As previously mentioned, retinol and retinoic acid are modulators of gene expression and are necessary for the proper development and growth of a conceptus ...
Regulatory mutations, instead of mutations in genes that encode for hormones and growth factors, support the known evolution of placental morphology, especially since the majority of hormone and growth factor genes are expressed in response to pregnancy, not during placental development. Researchers studied the regulatory landscape of placental ...
The placenta is used as a means of transferring nutrients from the mother to the fetus. The efficiency at which nutrients are transferred dictates the health and growth of the fetus. [10] Fetal weight/placental weight ratio, was commonly used to determine placental efficiency.
Soluble fms-like tyrosine kinase-1 (sFlt-1 or sVEGFR-1) is a tyrosine kinase protein with antiangiogenic properties. A non-membrane associated splice variant of VEGF receptor 1 (Flt-1), sFlt-1 binds the angiogenic factors VEGF (vascular endothelial growth factor) and PlGF (placental growth factor), reducing blood vessel growth through reduction of free VEGF and PlGF concentrations.

Betaarterivirus suid 1, commonly Porcine reproductive and respiratory syndrome virus (PRRSV), is a virus that causes a disease of pigs, called porcine reproductive and respiratory syndrome (PRRS), also known as blue-ear pig disease (in Chinese, zhū láněr bìng 豬藍耳病).
Normally, ovine placental mass increases until about day 70 of gestation, [45] but high demand on the placenta for fetal growth occurs later. (For example, research results suggest that a normal average singleton Suffolk x Targhee sheep fetus has a mass of about 0.15 kg at day 70, and growth rates of about 31 g/day at day 80, 129 g/day at day ...
SMEDI (an acronym of stillbirth, mummification, embryonic death, and infertility) is a reproductive disease of swine caused by Porcine parvovirus (PPV) [1] and Porcine enterovirus. The term SMEDI usually indicates Porcine enterovirus , but it also can indicate Porcine parvovirus , which is a more important cause of the syndrome. [ 2 ]
