Abstract: The aim of this study was to investigate the effect of sesamin (SES) added to in vitro culture (IVC) on the development of early mice embryos.The fertilized eggs of 6-week-old female Kunming mice were randomly divided into control group and different concentrations (10,50,100 μmol/L) SES groups.The apoptosis rate and total cell number in blastocysts were detected by Fluorescein-dUTP and Hoechst 33342 immunofluorescence staining,respectively.DCFH-DA was used to detect the levels of reactive oxygen species (ROS) in early embryos;The levels of glutathione (GSH) in early embryos were detected by CMF2HC;Early embryonic mitochondrial membrane potential intensity was measured using JC-1.The results showed that the segregation rate and blastocyst rate of SES groups were higher than those in control group,but there was no significant difference (P>0.05).The number of cells in 50 μmol/L SES group was significantly higher than that in control group (P<0.05),and the apoptosis rate was significantly lower than that in control group (P<0.05).Compared with control group,the ROS level in the 50 μmol/L SES group was significantly lower (P<0.05),and the GSH level and mitochondrial membrane potential level were significantly increased (P<0.05).The results showed that the addition of SES in IVC could increase the number of cells in blastocyst,decrease the apoptotic rate and the ROS level,increase the GSH level,improve the mitochondrial function of early embryos,reduce the damage of oxidative stress of embryos,and improve the quality of early embryonic development in mice.
