Artificial Activation of Oocytes from Sinclair Miniature Pigs [PDF]

open access: yesJournal of Applied Animal Research, 1996
Abstract Prather, R.S., Gibson, J. and Parry, T.W. 1996. Artificial activation of oocytes from Sinclair miniature pigs. J. Appl. Anim. Res., 10: 125–134. The experiments reported in this paper are designed to evaluate in Sinclair miniature pig oocytes a number of stimuli that are known to result in activation of domestic pig and mouse oocytes.

Cryopreservation of equine oocytes: looking into the crystal ball [PDF]

open access: yes, 2020
In vitro embryo production has evolved rapidly in the horse over the past decade, but blastocyst rates from vitrified equine oocytes remain quite poor and further research is needed to warrant application.

Effect of Mechanical Micro-Vibrations on The Efficiency of Leopard Inter-Species Somatic Cell Nuclear Transfer [PDF]

open access: yesCell Journal, 2022
Objective: Scarcity of oocytes for assisted reproduction in endangered species can be bypassed by interspecies somatic cell nuclear transfer (iSCNT). In Felids, domestic cat (Felis catus) oocytes can serve as recipients for the nucleus of the endangered ...

In vitro Activation of mouse oocytes through intracellular Ca2+ regulation

open access: yesJournal of Human Reproductive Sciences, 2020
Background: Ca2+ signaling pathway is suggested to play an essential role in mediating oocyte maturation. Aims: The aim of this study was to evaluate intracellular Ca2+ of resistant immature oocytes that failed to resume meiosis following subsequent in ...

Sperm-oocyte interplay: an overview of spermatozoon’s role in oocyte activation and current perspectives in diagnosis and fertility treatment

open access: yesCell & Bioscience, 2021
The fertilizing spermatozoon is a highly specialized cell that selects from millions along the female tract until the oocyte. The paternal components influence the oocyte activation during fertilization and are fundamental for normal embryo development ...

Hormad1 mutation disrupts synaptonemal complex formation, recombination, and chromosome segregation in mammalian meiosis [PDF]

open access: yes, 2010
Meiosis is unique to germ cells and essential for reproduction. During the first meiotic division, homologous chromosomes pair, recombine, and form chiasmata.

Homozygous Loss of Septin12, but not its Haploinsufficiency, Leads to Male Infertility and Fertilization Failure

open access: yesFrontiers in Cell and Developmental Biology, 2022
The SEPTIN12 gene has been associated with male infertility. Male Septin12+/− chimera mice were infertile, supporting the prevailing view that SEPTIN12 haploinsufficiency causes male infertility.

Expression profiles of genes regulating dairy cow fertility: recent findings, ongoing activities and future possibilities [PDF]

open access: yes, 2008
Subfertility has negative effects for dairy farm profitability, animal welfare and sustainability of animal production. Increasing herd sizes and economic pressures restrict the amount of time that farmers can spend on counteractive management Genetic ...

Maternal inheritance of twist and analysis of MAPK activation in embryos of the polychaete Annelid Platynereis dumerilii [PDF]

open access: yes, 2014
In this study, we aimed to identify molecular mechanisms involved in the specification of the 4d (mesentoblast) lineage in Platynereis dumerilii. We employ RT-PCR and in situ hybridization against the Platynereis dumerilii twist homolog (Pdu-twist) to ...
