Can extracellular vesicles from bovine ovarian follicular fluid modulate the in-vitro oocyte meiosis progression similarly to the CNP-NPR2 system?
(2020-11-01)
C-type natriuretic peptide (CNP) and its natriuretic peptide receptors subtype 2 (NPR2) are essential for the maintenance of oocyte meiotic arrest in different species. Extracellular vesicles (EVs) in bovine follicular ...
Stromal-derived factor 1 directly promotes genes expressed within the ovulatory cascade in feline cumulus oocyte complexes
(Springer/Plenum Publishers, 2018-03)
Purpose We hypothesized that the chemokine SDF1/CXCR4 system was present in feline cumulus-oocyte complexes (COCs) and that COCs cultured with SDF1 would directly upregulate gene expression in the ovulatory cascade. Methods ...

The effect of interaction between macromolecule supplement and oxygen tension on bovine oocytes and embryos cultured in vitro
(Cambridge University Press, 2009-11-01)
Aiming to improve in vitro production of bovine embryos and to obtain supplements to replace serum for in vitro maturation (IVM.), this study evaluated the effects of macromolecular supplementation of IMV medium (bovine ...

Coculture of porcine cumulus-oocyte complexes with porcine luteal cells during IVM: Effect on oocyte maturation and embryo development
(Csiro Publishing, 2020-11)
Coculture with somatic cells is an alternative to improve suboptimal in vitro culture conditions. In pigs, IVF is related to poor male pronuclear formation and high rates of polyspermy. The aim of this study was to assess ...
Induction of amphibian oocyte maturation by polyvalent cations and alkaline pH in the absence of potassium ions
(1979)
The maturation of Xenopus laevis oocytes was studied in media free of added potassium salts. Under these conditions maturation could be triggered by 1 mM Mn2+ and La3+ and, to a lesser extent, by 2-4 mM Ca2+ and Mg2+. ...
Líquido folicular eqüino na produção in vitro de embriões bovinos
(Universidade Federal de Santa MariaBrasilMedicina VeterináriaUFSMPrograma de Pós-Graduação em Medicina VeterináriaCentro de Ciências Rurais, 2002-01-07)
Follicular fluid has been used for in vitro embryo production, although it offers the risk of disease transmission. The use of heterologous follicular fluid can be an alternative to avoid infection. The effect of equine ...
