Laeverin/aminopeptidase Q induces trophoblast invasion during human early placentation.
BACKGROUND In primate placenta, extravillous trophoblast (EVT) invades maternal tissue in temporally- and spatially-regulated fashions. We previously identified a novel placenta-specific cell-surface aminopeptidase, laeverin/aminopeptidase Q, which is expressed on EVT-lineage cells in the fetal membrane. Laeverin possesses a peptide-binding site that is evolutionally unique to primates, suggest...
متن کاملComparative 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 کاملTrophoblast invasion and placentation: molecular mechanisms and regulation.
Trophoblast invasion is a key process during human placentation. This event constitutes the basis of the conversion of the uterine spiral arteries, a process which allows an adequate vascular connection between the intervillous space and the maternal blood flow. Trophoblast invasion is transient, with stringent spatial and temporal control. Preeclampsia, a leading cause of maternal and fetal mo...
متن کاملPromoter Hypomethylation of Maspin Inhibits Migration and Invasion of Extravillous Trophoblast Cells during Placentation
OBJECTIVE Extravillous trophoblast (EVT) cells invade the endometrium and the maternal spiral arterioles during the first trimester. Mammary Serine Protease Inhibitor (Maspin, SERPINB5) plays a putative role in regulating the invasive activity of cytotrophoblasts. The maspin gene is silenced in various cancers by an epigenetic mechanism that involves aberrant cytosine methylation. We investigat...
متن کاملExpression of heparin-binding EGF-like growth factor in term chorionic villous explants and its role in trophoblast survival.
Heparin-binding EGF-like growth factor (HBEGF) induces trophoblast extravillous differentiation and prevents apoptosis. These functions are compromised in preeclampsia. Because HBEGF is downregulated in placentas delivered by women with preeclampsia, we have examined its expression and cytoprotective activity in term villous explants. Chorionic villous explants prepared from non-pathological pl...
