Abstract:

This experiment was conducted to study the effect of oviduct epithelial cells co-culture on the development of early embryos, and explored the mechanisms of oviduct epithelial cells co-culture on overcoming the developmental arrest in mouse. Mouse oviduct epithelial cell line was purified and used to co-culture the zygotes, H2O2 contents in embryos were measured by DCHFDA, MTT was used to measure the activity of epithelial cells, RT-PCR was applied to test the transcriptions of CAT and GPX genes. Oviduct epithelial cells co-culture can significantly improve the early 2-cell and 4-cell rates (P0.05), the blastocyst rate was also increased (P0.05). Oviduct epithelial cells co-culture can decrease the H2O2 content in early 2-cell embryos (P<0.05). Also there was a deposit of H2O2 in the arrested embryos, the rates of typeand arrested embryos were decreasedP>0.05),type was increasedP0.05by oviduct epithelial cells co-culture. On the other side, the cellular activity was improved (P0.05) when embryos developed to early 2-cell phase, at the same time, transcriptions of CAT and GPX were increasedP>0.05. Those results indicated that oviduct epithelial cell co-culture can improve the development of embryos by cell-cell contact to decrease the reactive oxygen species content in embryos, overcome developmental arrest and promote embryo development.
