Quality control in oocytes by p63 is based on a spring-loaded activation mechanism on the molecular and cellular level

open access: yeseLife, 2016
Mammalian oocytes are arrested in the dictyate stage of meiotic prophase I for long periods of time, during which the high concentration of the p53 family member TAp63α sensitizes them to DNA damage-induced apoptosis.

Serous papillary adenocarcinoma possibly related to the presence of primitive oocyte-like cells in the adult ovarian surface epithelium: a case report

open access: yesJournal of Ovarian Research, 2011
Introduction The presence of oocytes in the ovarian surface epithelium has already been confirmed in the fetal ovaries. We report the presence of SSEA-4, SOX-2, VASA and ZP2-positive primitive oocyte-like cells in the adult ovarian surface epithelium of ...

Altered germline cyst formation and oogenesis in Tex14 mutant mice

open access: yesBiology Open, 2021
During oocyte differentiation in mouse fetal ovaries, sister germ cells are connected by intercellular bridges, forming germline cysts. Within the cyst, primary oocytes form via gaining cytoplasm and organelles from sister germ cells through germ cell ...

Macromolecules Influence Cellular Competence and Expression Level of IGFs Genes in Bovine Oocytes In Vitro

open access: yesAnimals, 2022
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 ...

Decreased oocyte quality in patients with endometriosis is closely related to abnormal granulosa cells

open access: yesFrontiers in Endocrinology, 2023
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 ...

Germ Cell Responses to Stress: The Role of RNP Granules

open access: yesFrontiers in Cell and Developmental Biology, 2019
The ability to respond to stress is critical to survival for animals. While stress responses have been studied at both organismal and cellular levels, less attention has been given to the effect of stress on the germ line. Effective germ line adaptations
