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.

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

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.

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 ...

Does variation in egg structure among five populations of Atlantic salmon (Salmo salar) influence their survival in low oxygen conditions? [PDF]

open access: yesRoyal Society Open Science, 2019
Oxygen supply to the salmonid egg surface can be limited by external factors such as sedimentation and groundwater upwelling, while the egg membrane itself can impede diffusion from the egg surface to the embryo. Therefore, the structure of egg membranes

Identification of chorion genes and RNA interference-mediated functional characterization of chorion-1 in Plutella xylostella

open access: yesJournal of Integrative Agriculture, 2022
Choriogenesis is the last step of insect oogenesis, a process by which the chorion polypeptides are produced by the follicular cells and deposited on the surface of oocytes in order to provide a highly specialized protective barrier to the embryo.

The cellular localization of chorionic somatomammotrophin in ovine chorion [PDF]

open access: yesReproduction, 1982
Sections of Days 12 to 55 sheep chorion, embedded at low temperature in glycol methacrylate, were exposed to rabbit anti-ovine chorionic somatomammotrophin (oCS) to ascertain the distribution of oCS. This hormone was first detectable on Day 14, when the cytoplasm of each chorionic cell displayed a low level of fluorescence surrounding droplets which ...
