Abstract (sommario):

The mammalian zona pellucida surrounding ovulated eggs mediates sperm binding at fertilization, provides a postfertilization block to polyspermy, and facilitates passage of pre-implantation embryos down the oviduct. Although the three zona proteins (ZP1, ZP2, ZP3) are well conserved, mammalian fertilization is relatively specific and human sperm do not bind to the mouse zona pellucida. There are considerable in vitro data that ZP3 acts as a primary sperm adhesion molecule in mice and, by analogy, a similar role has been postulated for human ZP3. Genetically altered mice lacking ZP3 (Zp3(tm/tm)

Abstract (sommario):

SummaryIn order to understand the role of the protein zona pellucida 2 in fertilization, an antibody against a central segment of the zona pellucida 2 peptide, segment 190–505 (Z2eH), was prepared. The influence of the antibody on sperm–zona interaction was tested using the sperm–egg binding assay. The effect of the antibody on fertility was evaluated by passive immunization with anti-Z2eH antibody. Immunohistochemical assay showed that an antibody from rabbit reacted specifically with the natural zona pellucida on mouse ovarian sections. Immunofluorescence assay showed that the antibody bound

Abstract (sommario):

Past studies from this laboratory have suggested that mouse sperm binding to the egg zona pellucida is mediated by a sperm galactosyltransferase (GalTase), which recognizes and binds to terminal N-acetylglucosamine (GlcNAc) residues in the zona pellucida (Shur, B. D., and N. G. Hall, 1982, J. Cell Biol. 95:567-573; 95:574-579). We now present evidence that directly supports this mechanism for gamete binding. GalTase was purified to homogeneity by sequential affinity-chromatography on GlcNAc-agarose and alpha-lactalbumin-agarose columns. The purified enzyme produced a dose-dependent inhibition

Abstract (sommario):

Fertilization requires taxon-specific gamete recognition, and human sperm do not bind to zonae pellucidae (ZP1–3) surrounding mouse eggs. Using transgenesis to replace endogenous mouse proteins with human homologues, gain-of-function sperm-binding assays were established to evaluate human gamete recognition. Human sperm bound only to zonae pellucidae containing human ZP2, either alone or coexpressed with other human zona proteins. Binding to the humanized matrix was a dominant effect that resulted in human sperm penetration of the zona pellucida and accumulation in the perivitelline space, whe

Our objective was to identify any changes that occur in the composition of the porcine zona pellucida during development of the 2- to 4-cell embryo from the oocyte. Oocytes, unfertilized eggs and single and 2- to 4-cell embryos have been recovered surgically and their zonae pellucidae 125I-labelled and analysed individually by sodium dodecyl sulphate-polyacrylamide gel electrophoresis (SDS-PAGE). The zonae from ovulated eggs possessed two major glycoproteins Mr 250000 and 90000 which were absent from follicular oocytes but present in the fluid from the oestrus, but not luteal, oviduct.

Abstract (sommario):

SummaryMammalian acrosin is a protease present as a zymogen in the acrosome of a non-reacted mammalian sperm, and in vitro is able to carry out limited hydrolysis of homologous and heterologous zonae pellucidae. On the other hand, sulphated polymers and zona pellcida glycoproteins bind to acrosin on a domain different from the active site, named the polysulphate binding domain (PSBD). Thus it is believed that acrosome-reacted spermatozoa bind to glycan chains of the zona pellucida through PSBD participating as secondary binding receptor. The aim of the present work was to study the role of PSB

Abstract (sommario):

The zona pellucida is an extracellular structure at the direct interface between the maternal and embryonic sides, through which all signals of the embryo–maternal dialogue as well as nutritional factors have to pass. Up to now there has been no investigation as to whether in vitro culture influences the structure of the zona pellucida compared to that of in vivo embryos. Therefore, in vitro (oocyte, zygote, 2-, 4-, 8-, 16-cell, morula, and Day 7 blastocyst, using the protocol published by Nganvongpanit et al. 2006 Reproduction 131, 861–874) and in vivo (zygote, 4-cell, morula, and blastocyst)

Abstract (sommario):

ABSTRACT: Hyaluronic acid (HA) not only surrounds the zona pellucida as part of the cumulus matrix but also is present throughout the zona pellucida and the perivitelline space of many mammalian oocytes. However, most in vitro techniques to study sperm—oocyte interaction eliminate HA from the oocyte through enzymatic digestion and/or do not expose sperm to HA prior to zona pellucida binding. This study explores the effect of preincubation of sperm or oocytes with HA on sperm—zona pellucida binding and subsequent acrosome reaction of bound sperm.

Abstract (sommario):

The extracellular zona pellucida surrounds ovulated eggs and mediates gamete recognition that is essential for mammalian fertilization. Zonae matrices contain three (mouse) or four (human) glycoproteins (ZP1–4), but which protein binds sperm remains controversial. A defining characteristic of an essential zona ligand is sterility after genetic ablation. We have established transgenic mice expressing human ZP4 that form zonae pellucidae in the absence of mouse or human ZP2. Neither mouse nor human sperm bound to these ovulated eggs, and these female mice were sterile after in vivo insemination

Abstract (sommario):

The zona pellucida surrounding the egg and pre-implantation embryo is required for in vivo fertility and early development. Explanatory models of sperm–egg recognition need to take into account the ability of sperm to bind to ovulated eggs, but not to two-cell embryos. For the last two decades, investigators have sought to identify an individual protein or carbohydrate side chain as the ‘sperm receptor’. However, recent genetic data in mice are more consistent with the three-dimensional structure of the zona pellucida, rather than a single protein (or carbohydrate), determining sperm binding.

Abstract (sommario):

The ability of the zona pellucida to mediate the species specific recognition of spermatozoa is due to a glycoprotein constituent of this structure, known as ZP3. In view of its important role in the initiation of fertilization, ZP3 has been identified as a suitable candidate for the development of a contraceptive vaccine. In order to generate recombinant marmoset ZP3 for immunization purposes a full length 1.3 kb insert encoding for marmoset ZP3 was cloned downstream of the malE gene to generate a fusion protein containing marZP3 and a maltose binding domain. This protein was found to be gene

The glycoconjugates of the oviduct epithelial lining of the brushtail possum around the time of ovulation were also examined to determine if there was any contribution of the oviductal secretions to the post-ovulatory ZP.

Abstract (sommario):

Abstract Despite the development of assisted reproduction technologies and significant advances in reproductive biology and medicine over the years the cause of infertility remains unexplained in 10–20% of cases. The cause of infertility in these cases may be connected to problems in fertilization or implantation and genetic factors may play a part in this. The zona pellucida (ZP) is an extracellular matrix surrounding the oocyte and early-stage embryos. It is important for folliculogenesis, fertilization and implantation. In humans, it is composed of four known ZP glycoproteins that all show

Hardening of the zona pellucida over the cell fertilization cycle is a well-recognized phenomenon and has been investigated using contact methods to measure shear and bending elasticity from indentation and micropipette aspiration [2, 3]. However, the area elasticity of the ZP, which provides resistance to cell swelling under variable osmotic environments, has not yet been reporte
