Supplementation of porcin in vitro maturation medium with FGF2, LIF, and IGF1 enhances cytoplasmic maturation in prepubertal gilts oocytes and improves embryo quality [PDF]

, 2022
In porcine production (IVP) systems, the use of oocytes derived from prepubertal gilts, whilst being commercially attractive, remains challenging due to their poor developmental competence following maturation (IVM). Follicular fluid contains important

Effects of the preservation medium and storage duration of domestic cat ovaries on the maturational and developmental competence of oocytes in vitro

The Journal of Reproduction and Development, 2022
We examined the effectiveness of saline, Euro-Collins solution (EC), and ET-Kyoto solution (ET-K) as preservation media for the cold storage of feline ovaries. Ovaries were maintained in these media at 4°C for 24, 48, or 72 h until oocyte retrieval.

Improvement of oocyte competence and in vitro oocyte maturation with EGF and IGF-I in Guinea pig model [PDF]

, 2023
2023 Acuerdos transformativos CRUEIn vitro maturation (IVM) system is an alternative method to superovulation protocols to obtain mature oocytes. Epidermal Growth Factor (EGF) and Insulin-like Growth Factor I (IGF-I) have been widely used in IVM medium ...

cAMP Modulators before In Vitro Maturation Decrease DNA Damage and Boost Developmental Potential of Sheep Oocytes [PDF]

, 2021
To date, the underlying mechanisms by which cAMP modulators act during in vitro maturation to improve oocyte developmental competence are poorly understood. Here, we sought to fill this knowledge gap by evaluating the use of phosphodiesterase inhibitor 3-

Protease mediated maturation of HIV: Inhibitors of protease and the maturation process [PDF]

, 2012
Protease-mediated maturation of HIV-1 virus particles is essential for virus infectivity. Maturation occurs concomitant with immature virus particle release and is mediated by the viral protease (PR), which sequentially cleaves the Gag and Gag-Pol ...

Changes in acetylation of lysine 5 on histone H4 in canine oocytes following in vitro maturation [PDF]

, 2017
Post-translational modifications of histones, such as acetylation, are involved in regulating chromatin remodelling and gene expression. Proper in vitro maturation (IVM) of canine oocytes, for many reasons, is up to now inefficient.

Rab3D is critical for secretory granule maturation in PC12 cells. [PDF]

, 2013
Neuropeptide- and hormone-containing secretory granules (SGs) are synthesized at the trans-Golgi network (TGN) as immature secretory granules (ISGs) and complete their maturation in the F-actin-rich cell cortex.

Effects of gonadotropin-exposed medium with high concentrations of progesterone and estradiol-17b on in vitro maturation of canine oocytes [PDF]

, 2009
During the process of maturation in the oviduct, canine oocytes in the germinal vesicle stage are exposed to decreasing levels of estradiol-17b and increasing levels of progesterone.

Comparison of Quinn's Advantage fertilization medium and tissue culture medium 199 for in vitro maturation of oocytes

Taiwanese Journal of Obstetrics & Gynecology, 2014
Objective: The purpose of the study was to compare the Quinn's Advantage fertilization medium (Q1) and the tissue culture medium 199 (TCM199) for in vitro maturation (IVM) of oocytes and ammonium production during IVM. Materials and methods: The immature
