Ion currents modulating oocyte maturation in animals
, 2013 Growing oocytes are arrested at the first prophase of meiosis which is morphologically identified by the presence of a large and vesicular nucleus, called germinal vesicle.

Somatic cell reprogramming for Parkinson's disease treatment
Ibrain, Volume 11, Issue 1, Page 59-73, Spring 2025.The fundamental purpose of cell reprogramming to treat Parkinson's disease is to generate dopaminergic neurons (DAN) and do transplantation. There are two ways to accomplish this. One method is to induce cells into induced DA neurons (iDAN) directly or to induce cells into induced pluripotent stem cells and ultimately into iDAN in vitro. Another option

DNA methylation mechanisms in the maturing and ageing oocyte
Epigenetics & ChromatinOocyte maturation involves both nuclear and cytoplasmic processes that are critical for the acquisition of oocyte competence. Granulosa cells, surrounding the oocyte, play a pivotal role in the maturation process, with mechanisms such as cAMP signaling ...

Characterization of Oocyte Maturation in Diabetic Mice
, 2002 Oogenesis is the process by which large precursor cells, primordial germ cells, differentiate into mature germ cells in the female. This process includes mitotic divisions to increase the number of precursor cells and meiosis to produce haploid gametes ...

International Journal of Gynecology &Obstetrics, EarlyView.Abstract Intrauterine insemination (IUI) is a widely used first‐line fertility treatment, yet its success rates vary considerably. This review synthesizes evidence from peer‐reviewed studies published between 2000 and 2024, including randomized controlled trials, cohort and case–control studies, as well as systematic and narrative reviews identified ...

Porcine oocyte maturation in vitro : role of cAMP and oocyte-secreted factors: a practical approach [PDF]
, 2016 Polyspermy or the penetration of more than one sperm cell remains a problem during porcine in vitro fertilization (IVF). After in vitro culture of porcine zygotes, only a low percentage of blastocysts develop and their quality is inferior to that of in ...

International Journal of Gynecology &Obstetrics, EarlyView.Abstract Background Poor ovarian response (POR) complicates a substantial proportion of in vitro fertilization (IVF) cycles, frequently causing cycle cancellation and suboptimal reproductive outcomes. Conventional follicular‐phase ovarian stimulation (FPOS) protocols often yield limited results, prompting the evaluation of alternative strategies such ...

Role of the Hyaluronan receptor CD44 during porcine oocyte maturation
, 2007 Previous of our study have been shown that CD44, the principal receptor of hyaluronan, is present in cumulus cell during oocyte maturation.Although hyaluronan-CD44 interaction has been implicated in cumulus expansion and/or oocyte maturation, the full ...
