This study was conducted to examine the effect of culture supernatant of bovine oviductal epithelial cell(BOEC) on in vitro development of mouse embryos. To obtain the culture supernatant, ampullary epithelial cell, ithmic epithelial cell and ciliated eptithelial cell of bovine oviduct were cultured in Ham's F-10 su, pp.emented with 10% FCS. The development rates of mouse embryos to blastocyst stage were significantly(P<0.05) higher in BOEC-culture supernatant(72.3∼82.3%) than in Ham's F-10(50.7%). The proportions of embryonic development into hatched blastocysts were significantly(P<0.05) higher in ampullary cell supernatant(43.2%), ithmic cell supernatant(48.4%) and ciliated cell supernatant (27.7%) than in Ham's F-10(14.4%). On the other hand, the effect of ciliated cell supernatant was lower than those of other cell supernatants(P<0.05). And there was no difference between ampullary cell supernatant and ithmic cell supernatnat.
