T1 - Subnormal zona pellucida change in parthenogenetic mouse embryos. AU - Mintz, Beatrice. AU - Gearhart, John D. PY - Y1 - N2 - Parthenogenetic mouse embryos were obtained by the method of electrical stimulation of eggs in vivo (Tarkowski et al., ), and their developmental retardation and limited viability were by: Spontaneous acrosome reaction. Spermatozoa can initiate the acrosomal reaction well in advance of reaching the zona pellucida, as well as in vitro in an appropriate culture medium. This is referred to as spontaneous acrosome reaction (SAR). It is now known that in a certain sense, this phenomenon is physiologically normal across mammalian species. Zona Pellucida Glycoprotein 1 (ZP1) Antigen Profile Protein Summary The mammalian zona pellucida, which mediates species- specific sperm binding, induction of the acrosome reaction and prevents post-fertilization polyspermy, is composed of three to four glycoproteins, ZP1, ZP2, ZP3, and ZP4.

Immunocontraception is the use of an animal's immune system to prevent it from fertilizing offspring. Contraceptives of this type are not currently available for human use. Typically immunocontraception involves the administration of a vaccine that induces an adaptive immune response which causes an animal to become temporarily infertile.
Contraceptive vaccines have been used in numerous. (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.
This thick matrix is thought to be formed by secretions from the oocyte and the follicle granulosa cells and in human oocytes consists of four types of zona pellucida glycoproteins ZP1, ZP2, ZP3 and ZP4.
Porcine zona pellucida (PZP) immunocontraception was investigated for possible use in free-roaming wild horses in the western USA. A protocol of two injections ( weeks apart) of vaccine lasting 1 year was first used and a single-injection controlled-release vaccine of 1 Cited by: The zona pellucida (ZP) is an extracellular matrix surrounding ovarian oocytes, ovulated eggs and preimplantation embryos.
It plays several important roles at different stages of reproduction. Its constituent glycoproteins are expressed specifically in the ovary. It is thus possible to produce autoantibodies to ZP proteins that interfere with reproductive functions including folliculogenesis Cited by: 3.
Bruce M. Carlson, in Reference Module in Biomedical Sciences, Attachment to and Penetration of the Zona Pellucida. The zona pellucida, which is 13 μm thick in humans, consists principally of four glycoproteins – ZP 1 to 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. zona [zo´nah] (L.) 1. zone. herpes zoster. zona fascicula´ta the thick middle layer of the adrenal gland. zona glomerulo´sa the outermost layer of the adrenal cortex.

The ZP appears during oocyte growth, and blastocyst stage embryos hatch from the ZP prior to implanting in the uterus.

Porcine zona pellucida (PZP) immunocontraception was developed to provide a more humane, effective, and inexpensive method of population regulation for wildlife species. It has been used to regulate populations of several species including white tailed deer (Odocoileus virginianus), elk (Cervus elaphus), black bear (Ursus americanus), and the feral horse (Equus ferus caballus) with varying Author: Cassandra M.V.
Nuñez. Zona pellucida (ZP) is a glycoproteinaceous translucent matrix that surrounds the mammalian oocyte and plays a critical role in the accomplishment of fertilization. In humans, it is composed of 4 glycoproteins designated as ZP1, ZP2, ZP3 and ZP4, whereas mouse ZP is composed of ZP1, ZP2 and ZP3 (Zp4 being a pseudogene).Cited by: Population control utilizing ovarian zona pellucida (ZP) antigens for immunocontraception has been successful in a variety of overpopulated “pest” species.
The use of ZP immunization is only effective in females and does not usually inhibit hormonal cycling , , .Cited by: Component of the zona pellucida, an extracellular matrix surrounding oocytes which mediates sperm binding, induction of the acrosome reaction and prevents post-fertilization polyspermy.
The zona pellucida is composed of 3 to 4 glycoproteins, ZP1, ZP2, ZP3, and ZP4. ZP1 ensures the structural integrity of the zona pellucida. The advent of immunocontraception with porcine zona pellucida (PZP) has all but revolutionized wild horse management, providing a more humane method of population control than earlier strategies.
Porcine Zona Pellucida (PZP) Contraception The proposed action as stated on page 7 of this EA would exempt “mares ages unless they have produced foals, or are part of a large bloodline.” This is reminiscent of the approach taken with the Assateague Island wild horse population. The zona pellucida is a protein membrane shell that coats an egg as it develops in the ovary.
The shell helps to regulate fertilization and remains in place until implantation. To facilitate successful conception, the shell must be the appropriate thickness, allowing sperm to permeate the casing, and for the embryo to "hatch" from the shell at.
Abstract. Mammalian eggs and embryos are enclosed and presumably protected by an extracellular shell termed the zona pellucida (Fig. There has been intense interest in the zona pellucida in recent years because of increased recognition of the importance of the zona in fertilization and because of the developments of methods to isolate zonae pellucidae, to assay sperm binding to zonae Cited by: and the perceived environmental risks of pesticide use.
The development of immunocontraception for population control of coyotes could result in a more acceptable alternative to poisons.
Immunocontraception using porcine zona pellucida (PZP) would allow normal estrus in the female and therefore normal male-female pair-bonding. Expression of four zona pellucida genes (ZP1, ZP2, ZP3 and ZPB), in the cDNA preparations derived from human oocytes was detected by PCR with the primers given in Table I.
Primers for detection of the ubiquitously expressed genes β ‐actin and hypoxanthine phosphoribosyl transferase (HPRT) as control genes are also given in Table by: Porcine zona pellucida immunocontraception: Long-term health effects on white-tailed deer Admin T+ Tags: physiological effects, porcine zona pellucida, PZP | The Journal of Wildlife Management ().
Zona pellucida (ZP), the extracellular glycoprotein matrix surrounding the mammalian oocyte is composed of three distinct glycoproteins that have been classified on the basis of the size of their mRNA transcripts as ZPA, ZPB, and ZPC where ZPA is the longest and ZPC the smallest (Harris.,et al ).

could result in a more acceptable alternative to poisons. Immunocontraception using porcine zona pellucida (P72) would allow normal estrus in the female and therefore normal male-female pair-bonding. Coyotes are mon-estrus, therefore P72 contraception during the breeding season of February and March could provide year-round protection.
The zona pellucida protects the egg and the early embryo before implantation. Its structure seems simple—in humans it contains four kinds. The acrosome is decomposed during sperm passage through the zona pellucida. In monotremes, marsupials, sheep, and cattle, coronal cells become almost completely dispersed from the ovum shortly before or soon after ovulation (Figure ).
The zona pellucida is the only barrier through which spermatozoa must pass in these species. Disclaimer. All content on this website, including dictionary, thesaurus, literature, geography, and other reference data is for informational purposes only. ZPI - Zona Pellucida Glycoprotein.
