背景介绍

  • PAG constitute a group of pregnancy-specific proteins secreted by the chorionic epithelium (trophectoderm) of the placenta. The proteins whose cDNA sequences have so far been identified are bovine and ovine PAG1, bovine PAG2, porcine PAG1 and PAG2, and equine PAG. bPAG1, also known as pregnancy-specific protein B, becomes detectable in maternal blood soon after implantation is initiated and can be used to diagnose pregnancy. The synthesis of bPAG1 is localized to a subpopulation of binucleate cells within the trophectoderm , which probably have an endocrine function, since they possess secretory granules that contain the hormone placental lactogen and PAG1. As implantation is initiated these binucleate cells migrate from the trophectoderm and fuse with uterine epithelial cells. They then release the contents of their secretory granules directly into the maternal system.
