The effects of electroporation on viability and quality of in vivo-derived bovine blastocysts

open access: yesThe Journal of Reproduction and Development, 2019
The introduction of exogenous molecules into embryos is required for analyses of molecular dynamics and specific gene functions during early embryonic development. Electroporation is an effective method to transport exogenous molecules into cells, but is

Expression of Tas1 taste receptors in mammalian spermatozoa [PDF]

open access: yes, 2012
Background: During their transit through the female genital tract, sperm have to recognize and discriminate numerous chemical compounds. However, our current knowledge of the molecular identity of appropriate chemosensory receptor proteins in sperm is ...

Defining bioassay conditions to evaluate sperm/zona interaction: Inhibition of zona binding mediated by solubilized human zona pellucida [PDF]

open access: yes, 1996
Objective: Our goal was to study the influence of solubilized human zonae pellucidae on zona binding potential and acrosome reaction. Materials and Methods: Zona pellucida (ZP) solutions were prepared by dissolving zona in acidic buffer, NaH2PO4 (pH 2.5),

002. PIG SPERM EGG INTERACTION AND FORMATION OF A ZONA PELLUCIDA BINDING COMPLEX [PDF]

open access: yes, 2010
In order to achieve fertilization sperm cells first need to successfully interact with the zona pellucida. Before reaching the zona pellucida the sperm cell undergoes extensive remodeling both in the male and female genital tract.

Sperm binding to the pig zona pellucida and inhibition of binding by solubilized components of the zona pellucida [PDF]

open access: yesReproduction, 1989
Summary. An assay to determine the binding of pig spermatozoa to the zona pellucida (ZP) of pig oocytes was developed using conditions compatible with in-vitro fertilization of pig eggs and with pig sperm penetration of zona-free hamster ova. These conditions were used to define which of the pig oocyte ZP components were involved in sperm binding by a ...

CRISPR/Cas9 + AAV-mediated Intra-embryonic Gene Knocking in Mice

open access: yesBio-Protocol, 2019
Intra-embryo genome editing by CRISPR/Cas9 has enabled rapid generation of gene knockout animals. However, large fragment knock-in directly into embryos’ genome is still difficult, especially without microinjection of donor DNA.

Glycodelin-A interacts with fucosyltransferase on human sperm plasma membrane to inhibit spermatozoa-zona pellucida binding [PDF]

open access: yes, 2007
Fertilization depends on successful binding of the spermatozoa to the zona pellucida of the oocyte. Glycodelin-A inhibits spermatozoa-zona pellucida binding.

Influential effect of age on oocyte morphometry, fertilization rate and embryo development following IVF in mice

open access: yesMiddle East Fertility Society Journal, 2018
Changes of oocyte quality and decreasing of ovarian follicle reserve in advanced age are the major challenges in infertility treatments. One factor associated with aging is the thickness of zona pellucida, which has adverse relation with embryo score ...

Two candidate genes for recurrent pregnancy loss and infertility: Could ZP3 and UPK3B give us new diagnostic and therapeutic approach? [PDF]

open access: yesBioDiscovery, 2017
Introduction: Chromosomal indels are relatively common cytogenetic abnormalities. Nonetheless, clinical outcomes depend on the location, size and genes in deletion or duplication regions.
