Oocyte growth is a key step in forming mature eggs that are ready to be fertilized. The states and modifications of chromatin represent critical sources of information for this process.

Genome-wide methylation profile of mitochondrial DNA across bovine preimplantation development
This study characterized variations in the methylation profile of mitochondrial DNA (mtDNA) during initial bovine embryo development and correlated the presence of methylation with mtDNA transcription.

Fine morphological assessment of quality of human mature oocytes after slow freezing or vitrification with a closed device: a comparative analysis [PDF]
BACKGROUND: Human mature oocytes are very susceptible to cryodamage. Several reports demonstrated that vitrification might preserve oocyte better than slow freezing. However, this is still controversial.

Infertility and menstrual abnormalities in endometriosis patients are frequently caused by aberrant follicular growth or a reduced ovarian reserve. Endometriosis typically does not directly harm the oocyte, but rather inhibits the function of granulosa ...

NLRP2 controls age-associated maternal fertility [PDF]
Nucleotide-binding domain and leucine-rich repeat (NLR) proteins are well-known for their key roles in the immune system. Ectopically expressed NLRP2 in immortalized cell lines assembles an inflammasome and inhibits activation of the proinflammatory ...

Maturation of Oocytes in Vitro.
Only a fraction of oocytes present in the ovaries at birth are ever ovulated during the lifetime of a female mammal. In vitro maturation (IVM) offers the possibility to exploit what is a largely untapped biological resource.

LSD1 is essential for oocyte meiotic progression by regulating CDC25B expression in mice [PDF]
Mammalian oocytes are arrested at prophase I until puberty when hormonal signals induce the resumption of meiosis I and progression to meiosis II.

In vitro maturation (IVM) of mammalian oocytes, which influences subsequent in vitro development of embryos, is affected by the macromolecule content in culture media for the success of oocyte maturation competence, in which the cytoplasmic and nuclear ...
