Antioxidants and antioxidants with somatic cell co-culture, bovine oviduct epithelial cells(BOEC) and buffalo rat liver cells(BRLC), were studied as a mean of increasing the development and intracellular glutathione(GSH) concnetrations of bovine embryos derived from in vitro matured(IVM) and in vitro fertilized(IVF) oocytes. Cell numbers and intracellular GSH concentrations of blastocysts were also counted. The developmental rate beyond morula stages in CRlaa containing taurine(2.5mM), superoxide dismutase(SOD, 600U) and catalase(250U) were 1%, 75.0%, 64.8% and 62.3%, respectively. The developmental rate in antioxidant groups was significantly higher than in control(P<0.05). The intracellular GSH concentrations of blastocysts cultured in 0, 2.5mM taurine, 600U SOD and 250U catalase were 33.8pM, 39.3pM, 42.3pM and 54.8pM, respectively. This result indicated that the developmental rates and intracellular GSH concentrations of catalase group was significantly higher than any other groups(P<0.05). The developmental capacity in CRlaa plus various antioxidants co-cultured with BOEC were 55.3%(control), 74.1%(2.5mM taurine), 66.7%(600U SOD) and 70.7%(250U catalase) and in CRlaa plus various antioxidants co-cultured with BRLC in control, 2.5mM taurine, 600U SOD and 250U catalase were 63.8%, 75.5%, 71.0% and 73.5%, respectveily, the intracellular GSH concentrations of blastocyst embryos co-cultured with BOEC and BRLC in CRlaa with 0.25mM taurine, 600U SOD and 250U catalase were 73.4pM and 64.4pM, 79.9pM and 67.5pM, 82.3pM and 71.7pM, and 83.0pM and 80.0pM, respectively. Cell numbers of blastocysts were not difference in all experimental groups. These studies indicate that andtioxidants and antioxidant with somatic cell co-culture can increase the proportion of embryo that developed into morula and blastocysts, and the intracellular GSH concentrations of blastocyst embryos.
