Correlation of the position and status of the polar body from the fertilized oocyte to the euploid status of blastocysts

open access: yesFrontiers in Genetics, 2022
Polar bodies are tiny cells that are extruded during oocyte meiosis and are generally considered not essential for embryonic development. Therefore, polar bodies have been widely used as important materials for the preimplantation genetic diagnosis of ...

Interspecies somatic cell nuclear transfer is dependent on compatible mitochondrial DNA and reprogramming factors [PDF]

open access: yes, 2011
Interspecies somatic cell nuclear transfer (iSCNT) involves the transfer of a nucleus or cell from one species into the cytoplasm of an enucleated oocyte from another.

Survival of bovine blastocysts produced in vitro and vitrified in vitri-tip and vitri-top devices. [PDF]

open access: yesSPERMOVA, 2019
Vitrification is a new technique that has many potential advantages in mammalian oocytes and embryos. In the present work, the objective was to compare of post thawing survival rate by of blastocysts vitrified in vitro in two devices.

Prostaglandins in Swine Blastocysts [PDF]

open access: yesBiology of Reproduction, 1983
The activity of phospholipase A2 (PLA2) and the content of prostaglandins (PGF and PGE-A) in swine blastocysts were determined on Days 7 through 14 of gestation by using radioenzymatic and radioimmunoassay techniques. Both PLA2 activity and PG content increased in the blastocyst with age.

The Open Cryotop System Is Effective for the Simultaneous Vitrification of a Large Number of Porcine Embryos at Different Developmental Stages

open access: yesFrontiers in Veterinary Science, 2022
The Superfine Open Pulled Straw (SOPS) system is the most commonly used method for vitrification of pig embryos. However, this system only allows the vitrification of four to seven embryos per straw.

Transient Sperm Starvation Improves the Outcome of Assisted Reproductive Technologies

open access: yesFrontiers in Cell and Developmental Biology, 2019
To become fertile, mammalian sperm must undergo a series of biochemical and physiological changes known as capacitation. These changes involve crosstalk between metabolic and signaling pathways and can be recapitulated in vitro.
