The zona pellucida is an extracellular matrix that surrounds the plasma membrane of the egg cell. It helps protect the egg, and has an essential role in fertilization by sperm.

2024年2月21日 · The zona pellucida (ZP) is an extracellular matrix layer that forms between the cell membrane of the oocyte and the first layer of granulosa cells during primary ovarian follicle …

(Latin, zona pellucida = transparent zone) The zona pellucida (ZP) is a specialized extracellular matrix surrounding the developing oocyte (egg, ovum) within each follicle within the ovary.

2022年1月25日 · The zona pellucida (ZP) is a relatively thick extracellular matrix (ECM) that surrounds all mammalian oocytes, eggs, and preimplantation embryos, from monotremes that …

The zona pellucida (ZP) is the unique extracellular matrix surrounding the mammalian oocyte. During the fertilization process, sperm must first bind to and penetrate the zona before it …

The zona pellucida is a thick, transparent, noncellular layer or envelope of uniform thickness surrounding an oocyte. Under the light microscope, it appears as a radially striated layer …

2021年3月23日 · The zona pellucida (ZP) is an extracellular matrix that is synthesized during follicular development and finally surrounds the plasma membrane of the oocyte and …

The zona pellucida is a glycoprotein layer that surrounds the plasma membrane of an oocyte (egg cell) and plays a crucial role during fertilization. It serves as a protective barrier and provides …

The zona pellucida is a membrane composed of four glycoproteins (ZP1-4) that surrounds the plasma membrane of the mammalian oocyte. It is important for inducing the acrosome …

Zona pellucida is a translucent covering of glycoproteins around mammalian eggs. It helps the binding of sperms through species-specific fertilization to avoid polysperm.
