Abstract

OBJECTIVE
The purpose of the study was to determine the effects of co-culture with oviductal epithelial cells and Vero cells on mouse embryo. METHOD: For the control group, mouse embryos were cultured alone in Ham's F-10 with 10% FBS. Subcultured oviductal epithelial cell and Vero cell were cocultured in Ham's F-10 with 10% FBS with the mouse embryo and used as the treatment group. Development of mouse embryos were observed. Result: The development rate and hatching rate of embryos that cocultured with oviductal epithelial cell and Vero cell was significantly higher (p<0.05) than control group. When subcultured oviductal epithelial cells were co-cultured with mouse embryo, there was no significant difference in development rate and hatching rate among subculture step. When oviductal epithelial cells that have been frozen-thawed were co-cultured with mouse embryo, there was no significant difference in development rate and hatching rate among subculture step. No statistical significance was seen in the development rate and hatching rate between subcultured oviductal epithelial cells and frozen-thawed oviductal epithelial cells when cocultured with mouse embryo, Vero cells and frozen-thawed when cocultured with mouse embryo, and Vero cells and oviductal epithelial cells when cocultured with mouse embryo.
CONCLUSION
Oviductal epithelial cells and Vero cell may have a stimulatory role in early mouse embryonal development compared to control in vitro. As well, there is no significant difference in development rate and hatching rate among subculture step, when early mouse embryo was cocultured with cells that subcultured and frozen-thawed.
