| pubmed-article:15823615 | pubmed:abstractText | Prostaglandins (PGs) play a central role in primate parturition by their actions on uterine contractility and on cervical ripening. Rhesus monkey placentation is hemochorial and the endocrine events surrounding parturition are qualitatively similar to human pregnancy. Although there is an increase in PG production before the onset of labor, little is known about the cellular localization of the PGH synthase (PGHS) or the 15-hydroxy PG dehydrogenase (PGDH) in the fetal membranes of nonhuman primates and whether it changes at term in spontaneous labor or during preterm labor associated with infection. Placental corticotropin releasing hormone (CRH) and the glucocorticoid receptor (GR) have also been implicated as mediators in parturition by virtue of their roles in PG production. We utilized immunohistochemical methods to localize the inducible isoform PGHS-2, PGDH, GR and CRH in rhesus monkey amnion, chorion and attached decidua. Tissues were obtained at cesarean section during late pregnancy, in spontaneous labor at term and in premature labor induced by Group B streptococcal intraamniotic infection. Specific staining for immunoreactive (ir)-PGHS-2 was observed in amnion epithelial and mesenchymal cells and to a lesser extent in chorion and decidua. In contrast, ir-PGDH was localized primarily to the extravillous trophoblast layer of chorion. GR was localized to both the cytoplasm and nucleus of amnion epithelial cells, subepithelial fibroblasts, chorion trophoblasts and in decidua. Immunostaining for CRH was found in amnion and in scattered decidual cells but was most intense in the chorion trophoblast layer. There was no demonstrable change in this overall pattern of immunostaining in association with the onset of labor at term except for a decrease in staining for ir-PGDH in chorion. Experimental Group B streptococcal chorioamnionitis resulted in preterm labor and extensive necrosis of extravillous trophoblast cells with subsequent loss of chorionic ir-PGDH and relative sparing of ir-PGHS-2 in amnion epithelium which favors the net production of PGs. The expression pattern of these effectors in the rhesus monkey fetal membranes points to a functional role of PGs and glucocorticoids in the process of term and preterm parturition which is similar to that in human pregnancy. | lld:pubmed |
