Bacteria localization and chorion thinning among preterm premature rupture of membranes. [PDF]

open access: yesPLoS ONE, 2014
OBJECTIVE: Bacterial colonization of the fetal membranes and its role in pathogenesis of membrane rupture is poorly understood. Prior retrospective work revealed chorion layer thinning in preterm premature rupture of membranes (PPROM) subjects.

Chorion Alterations in Eyed-Stage Salmonid Eggs Farmed in La Araucanía, Chile: A Retrospective Study

open access: yesAnimals, 2021
The chorion is the primary envelop that protects the fish embryo against mechanical actions, pathogens, and abrupt changes in physical and chemicals conditions of the incubation medium. During embryo development, chorion alterations are not rare, but the

Cytokines in single layer amnion allografts compared to multilayer amnion/chorion allografts for wound healing [PDF]

open access: hybridJournal of Biomedical Materials Research. Part B - Applied biomaterials, 2014
Human amniotic membrane allografts have proven effective at improving healing of cutaneous wounds. The mechanism of action for these therapeutic effects is poorly understood but is thought to involve the resident growth factors present in near term ...

Cross-species insemination reveals mouse sperm ability to enter and cross the fish micropyle [PDF]

open access: yeseLife
Extracellular matrices surrounding eggs in fish (chorion) and mammals (zona pellucida [ZP]) regulate gamete recognition before fertilization, though their mechanisms differ.

The role of chorion on toxicity of silver nanoparticles in the embryonic zebrafish assay [PDF]

open access: yesEnvironmental Health and Toxicology, 2014
Objectives This study was designed to investigate how the size- and surface coating-dependent toxicity of silver nanoparticles (AgNPs) is influenced by the presence and absence of the chorion in an embryonic zebrafish assay.

Comparison of angiogenic, cytoprotective, and immunosuppressive properties of human amnion- and chorion-derived mesenchymal stem cells. [PDF]

open access: yesPLoS ONE, 2014
Although mesenchymal stem cells (MSCs) can be obtained from the fetal membrane (FM), little information is available regarding biological differences in MSCs derived from different layers of the FM or their therapeutic potential.

Function and failure of the fetal membrane: Modelling the mechanics of the chorion and amnion.

open access: yesPLoS ONE, 2017
The fetal membrane surrounds the fetus during pregnancy and is a thin tissue composed of two layers, the chorion and the amnion. While rupture of this membrane normally occurs at term, preterm rupture can result in increased risk of fetal mortality and ...

ATG3 Is Important for the Chorion Ultrastructure During Oogenesis in the Insect Vector Rhodnius prolixus

open access: yesFrontiers in Physiology, 2021
In insects, the last stage of the oogenesis is the choriogenesis, a process where the multiple layers of the chorion are synthesized, secreted, and deposited in the surface of the oocytes by the follicle cells. The chorion is an extracellular matrix that

Critical Role of the Cortical Alveolus Protease Alveolin in Chorion Hardening In Vivo at Medaka Fertilization

open access: yesBiomolecules, 2023
Alveolin is a cortical alveolus proteinase that is secreted in the perivitelline space (PVS) at fertilization to act on the chorion. Purified alveolin is known to induce chorion hardening in vitro by processing zona pellucida B (ZPB), a major chorion ...
