Post-Translational Modifications in Oocyte Maturation and Embryo Development

open access: yesFrontiers in Cell and Developmental Biology, 2021
Mammalian oocyte maturation and embryo development are unique biological processes regulated by various modifications. Since de novo mRNA transcription is absent during oocyte meiosis, protein-level regulation, especially post-translational modification (

Oocyte Competence Biomarkers Associated With Oocyte Maturation: A Review

open access: yesFrontiers in Cell and Developmental Biology, 2021
Oocyte developmental competence is one of the determining factors that influence the outcomes of an IVF cycle regarding the ability of a female gamete to reach maturation, be fertilized, and uphold an embryonic development up until the blastocyst stage ...

The Function of Cumulus Cells in Oocyte Growth and Maturation and in Subsequent Ovulation and Fertilization

open access: yesCells, 2021
Cumulus cells (CCs) originating from undifferentiated granulosa cells (GCs) differentiate in mural granulosa cells (MGCs) and CCs during antrum formation in the follicle by the distribution of location. CCs are supporting cells of the oocyte that protect

Novel Concepts for Inducing Final Oocyte Maturation in In Vitro Fertilization Treatment

open access: yesEndocrine Reviews, 2018
Infertility affects one in six of the population and increasingly couples require treatment with assisted reproductive techniques. In vitro fertilization (IVF) treatment is most commonly conducted using exogenous FSH to induce follicular growth and human

Effects of melatonin on in vitro oocyte maturation and embryo development in pigs [PDF]

open access: yesVeterinary World
Background and Aim: In vitro fertilization (IVF) efficiency in pigs remains suboptimal, partly due to oxidative stress during oocyte maturation and embryo development.

Lipid Metabolism Was Associated With Oocyte in vitro Maturation in Women With Polycystic Ovarian Syndrome Undergoing Unstimulated Natural Cycle

open access: yesFrontiers in Cell and Developmental Biology, 2021
ObjectiveHyperlipidemia are common polycystic ovarian syndrome (PCOS)-related metabolic dysfunctions and can adversely affect assisted reproductive technology (ART) outcomes in controlled ovarian hyperstimulation (COH) cycles. The objective of this study
