Zona pellucida - Wikipedia
The zona pellucida (Latin meaning "transparent zone") is the specialized area surrounding mammalian oocytes (eggs). It is also known as an egg coat. The zona pellucida is essential for oocyte growth and fertilization
Zona pellucida: Anatomy and function - Kenhub
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 development. This layer measures about 5 to 10 μm in thickness and is composed of four main glycoproteins: ZP1, ZP2, ZP3 and ZP4.

4 天之前 · (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.
Zona pellucida genes and proteins and human fertility - PMC
The zona pellucida (ZP) is an extracellular matrix (ECM) that surrounds all mammalian oocytes, eggs, and embryos and plays vital roles during oogenesis, fertilization, and preimplantation development.
Zona Pellucida - an overview | ScienceDirect Topics
The Zona Pellucida is an extracellular matrix that surrounds eggs and early embryos, playing a crucial role in initial gamete recognition, preventing polyspermy, and protecting the embryo during its journey through the oviduct before implantation.

The zona pellucida (ZP) is a relatively thick extracellular matrix (ECM) that surrounds all mammalian oocytes, eggs, and preimplantation embryos, from monotremes that lay eggs to placental mammals (Wassarman and Litscher, 2016; Wassarman and Litscher, 2021).
New Insights into the Mammalian Egg Zona Pellucida - PMC
The zona pellucida (ZP) is an extracellular matrix that is synthesized during follicular development and finally surrounds the plasma membrane of the oocyte and preimplantation embryo of mammals. ZP functions are related to important events that take place during oocyte formation, fertilization, and early embryo development.

Zona Pellucida - an overview | ScienceDirect Topics
The zona pellucida, which is 13 µm thick in humans, consists principally of four glycoproteins—ZP 1 to ZP 4. ZP 2 and ZP 3 combine to form basic units that polymerize into long filaments. These filaments are periodically linked by cross-bridges of ZP 1 and ZP 4 molecules ( Fig. 2.5 ).
