Feline Wharton’s jelly-derived mesenchymal stem cells as a feeder layer for oocytes maturation and embryos culture in vitro

open access: yesFrontiers in Veterinary Science, 2023
IntroductionDue to their capacity to release growth factors and cytokines, co-culture using mesenchymal stem cells has been considered a good alternative to promoting the maturation of the oocytes and the embryo’s development quality in vitro in ...

Embryo Genetics [PDF]

open access: yesGenes, 2021
Advances in embryo and reproductive genetics have influenced clinical approaches to overcome infertility. Since the 1990s, many attempts have been made to decipher the genetic causes of infertility and to understand the role of chromosome aneuploidies in embryo potential.

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.

The Effect of Light on Embryos and Embryo Culture [PDF]

open access: yesJournal of Reproductive and Stem Cell Biotechnology, 2012
In oviparous animals, the egg hatches outside of the body and is exposed to light; in some cases throughout the development of the fetus. In mammals, fertilization and the growth of embryos in vivo occurs in the dark but in human IVF, these embryos are exposed to variable light sources and intensities.

Determining Pollinizer Success Rates among Several Apple (Malus domestica L.) Cultivars Using Microsatellite Markers

open access: yesAgronomy, 2023
In order to determine the pollinizer success rates between twelve apple cultivars in 2021 and 2022, 671 apple embryos were collected from 19 different orchards in Ullensvang (southwestern Norway) and Svelvik (southeastern Norway).

Engineering the embryo [PDF]

open access: yesProceedings of the National Academy of Sciences, 2011
Generation of transgenic mice by pronuclear DNA injection into fertilized eggs has been well-established for over 30 y (1). However, it remains a rather crude approach: injected sequences randomly insert as concatamers, they can be mutagenic, and they have variable expression depending on the site of integration, a phenomenon called position effects ...

Pre-implantation mouse embryos cultured In vitro under different oxygen concentrations show altered ultrastructures [PDF]

open access: yes, 2020
Assisted Reproductive Technologies routinely utilize different culture media and oxygen (O2) concentrations to culture human embryos. Overall, embryos cultured under physiological O2 tension (5%) have improved development compared to embryos cultured ...

Uterine selection of human embryos at implantation [PDF]

open access: yes, 2014
Human embryos frequently harbor large-scale complex chromosomal errors that impede normal development. Affected embryos may fail to implant although many first breach the endometrial epithelium and embed in the decidualizing stroma before being rejected ...

Cloning of embryos [PDF]

open access: yesBioscientifica Proceedings, 2020
Nuclear transfer for the study of differentiation in amphibians has been used since the 1950s, but not until recently have the same procedures been applied successfully to some mammals. Nuclear transfer, as developed for the amphibian, is successful in sheep, cattle, rabbit, and pig, but not mouse embryos.
