1 lut 2012 · In this study, we investigate the formation of zona radiata, theca cell and granulosa cell in the teleost Pseudosctaena crocea. Four layers exist outside the oocyte plasamallea, i.e., theca cell layer, basal membrane, granulosa cell layer and zona radiata. Microvilli fully participates in the formation of zona radiata and granulosa cells. Three ...
16 paź 2007 · Zonagenesis is the process by which the egg envelope (variously labeled as the zona radiata, zona pellucida, vitelline envelope, or chorion) forms around the developing oocyte as a thick, highly differentiated acellular zone (see the reviews by Laale 1980 and Arukwe and Goksoyr 2003).
The oocyte that is released by ovulation is protected by a thick outer layer of granulosa cells known as the corona radiata and by the zona pellucida, a thick glycoprotein membrane that lies just outside the oocyte’s plasma membrane.
Zona pellucida and corona radiata are oocyte layers that help in the fusion of sperm with the oocyte. Find out the tabulated differences between zona pellucida and corona radiata, only at BYJU’S.
La zona radiata est une membrane d'oeuf épaissie et plutôt complexe de poissons Téléostéens, qui a souvent un aspect radié. Il est formé à la surface de l'oeuf par l' ooplasme , ou l'ooplasme et les cellules folliculaires et doit donc être considéré comme une véritable membrane vitelline .
