The placenta facilitates nutrient and gas exchanges between the mother and growing fetus. It does this through highly branched embryonic blood vessels called villi. In the mouse, villi start to form when the allantois attaches to the chorion. This attachment is mediated through a thin layer of mesothelium on the chorion, which becomes indistinguishable from the allantoic cells after attachment....

The effect of the culture supernatant of influenza virus (IV)-infected apoptotic and non-apoptotic cells on the differentiation of monocytes to macrophages was investigated. IV infection induced apoptotic DNA fragmentation in cultured chorion cells but not in amnion cells prepared from human foetal membrane tissue. To examine the differentiation of monocytes to macrophages, an adhesion assay wa...

Despite the widespread clinical use of oxytocin (OT) as a potent and specific stimulant of labor, previous research data have not supported a role for OT in the physiology of normal human parturition. We have demonstrated synthesis of OT mRNA in amnion, chorion, and decidua using Northern blot analysis, ribonuclease protection assays, and in situ hybridization. Probes directed towards both the ...

Brown trout (Salmo trutta) broodstock from a single population were separated prior to spawning and exposed to two different holding environments: a ‘raceway system’ and a ‘tank system’. Eggs were stripped from females and 13 measures of egg quality were collected, analysed individually, combined by principle components analysis into an integrated egg quality score which was validated against e...

The authors of the article investigated quantitative parameters placental chorion tree during physiological pregnancy and gestation against background iron deficiency anemia. It has been established that anemia in pregnant women inhibits development chorionic tree, which is explained by formation villi (through trophoblastic free processes) violation transition terminal to "specialized" villi. ...

The chorion patterns produced by progeny from crosses that were used to define the linked gene clusters, C h 1, C h 2 and C h 3 (strain C108 us. strain Ascoli) , were examined by two-dimensional gel electrophoresis (isoelectric focusing us. SDS/urea). Approximately 60 proteins were assigned to four previously defined chorion classes, A, B, C and H,, believed to represent the products of related...

Most animals are oviparous. However, the genes regulating egg shell formation remain not very clear. In this study, we found that Nilaparvata lugens Forkhead box transcription factor L2 (NlFoxL2) directly activated follicle cell protein 3C (NlFcp3C) to regulate chorion formation. NlFoxL2 and NlFcp3C had a similar expression pattern, both highly expressed in the follicular cells of female adults...
