Última Reactive oxygen species in bovine embryo in vitro production Biocell Dalvit,G.C.; Cetica,P.D.; Pintos,L.N.; Beconi,M.T.. Oxidative modifications of cell components due to the action of reactive oxygen species (ROS) is one of the most potentially damaging processes for proper cell function. However, in the last few years it has been observed that ROS participate in physiological processes. The aim of this work was to determine ROS generation during in vitro production of bovine embryos. Cumulus-oocyte complexes were recovered by aspiration of antral follicles from ovaries obtained from slaughtered cows and cultured in medium 199 for 22 h at 39ºC in 5% CO2: 95% humidified air. In vitro fertilization was carried out in IVF-mSOF with frozenthawed semen in the same culture conditions and embryo in vitro culture in IVC-mSOF at 90% N2: 5% CO2: 5% O2. ROS was determined in denuded... Tipo: Info:eu-repo/semantics/other Palavras-chave: Reactive oxygen species; Oxidative stress; Oocyte; Embryo; Bovine.
