Effect of -Mercaptoethanol and Cysteamine With Bovine Oviduct Epithelial Cells on Development and Intracellular Glutathione Concentrations of Bovine IVM/IVF Embryos
pp.269-276
The objective of this study was to investigate the effects of thiol compounds with bovine oviduct epithlial crlls(BOEC) co culture on development and intracellular glutathione(GSH) concentrations of bovine embryos derived from IVM /IVF oocytes. In experiment 1 and 2, embryos developed to 2~8 cell stage after in vitro fertilization were co-cultured with BOEC in CRaa with or without -mercaptoethanol(-ME) and cysteamine. The percentage of embryos that developed to morulae and blastocysts in 0,10, 25 and 5OM -ME with BOEC was 48.1, 64.0, 72.9 and 75.9%, respectively. Twenty-five and 5OM -ME groups were significantly higher than in 0 and 1OM - -ME groups(PM cysteamine with BOEC was 50.0, 53.2, 72.0 and 66.7%, respectively. Fifty M cysteamine group was significantly higher than any other groups (Paa with 0 and 5OM -ME or cysteamine were 68.5, 77.8, 78.7 and 80.0pM, respectively. Fifty M -ME group was significantly higher than that of control(P<0.05), but cysteamine group was not. Cell numbers of blastocysts were not difference in all experimental groups. These experiments indicate that -ME and cysteamine with BOEC co-culture can affect the development and intracellular GSH concentrations of bovine embryos produced by IVM /IVF docytes.
