Comparative aspects of trophoblast development and placentation
Based on the number of tissues separating maternal from fetal blood, placentas are classified as epitheliochorial, endotheliochorial or hemochorial. We review the occurrence of these placental types in the various orders of eutherian mammals within the framework of the four superorders identified by the techniques of molecular phylogenetics. The superorder Afrotheria diversified in ancient Afri...
متن کاملNeurological complications associated with pregnancy.
Prospective multidisciplinary audit from both hospital and community has identified neurological complications persisting for more than 6 weeks in association with pregnancy and delivery. They occurred at a frequency of 1 in 2530 deliveries in the North West Thames Region. Extradural analgesia was considered contributory to a neurological disorder in one of 13,007 patients. The woman had prolon...
متن کاملPolytene chromosomes in mouse trophoblast giant cells.
Mouse trophoblast giant cells undergo successive rounds of DNA replication resulting in amplification of the genome. It has been difficult to determine whether giant cell chromosomes are polyploid as in liver cells or polytene as in Dipteran salivary glands because the chromosomes do not condense. We have examined the pattern of hybridization of mouse giant cells with a variety of in situ chrom...
متن کاملN-glycodiversity of the Pregnancy-Associated Glycoprotein family (PAG) produced in vitro by trophoblast and trophectoderm explants during implantation, placentation and advanced pregnancy in the pig.
The PAG family is encoded by distinct genes expressed in extra-embryonic chorionic membranes (TR--trophoblast, TRD--trophectoderm) of various pregnant mammals. The objective of our study was to determine N-glycodiversity of porcine PAG protein family (pPAG) produced in vitro by TR or TRD explants of gilts (n=26) throughout pregnancy (16-77 dpc). Explants were cultured for over 1200 h (TR, 16 dp...
متن کاملThe Relationship of Nausea and Vomiting during Pregnancy with Pregnancy Complications
Background & aim: Nausea and vomiting are among the most common complaints during pregnancy observed in patients with severe pregnancy outcomes. The purpose of this study was to investigate the relationship of nausea and vomiting during pregnancy (NVP) with some pregnancy complications. Methods: This cross-secti...
متن کاملGene Amplification: Trophoblast Giant Cells Use All the Tricks
Evolutionary gene duplication, developmental endoreduplication and selective gene amplification are alternative strategies for increasing gene copy number. When these processes occur together, things get really interesting, and new work shows that is the lifestyle of cells in the placenta.
