영어초록

In vitro developmental ability of early preimplantation monse embryos was shown to be depend on the embryonic stages, media and snpplements and their interaction(Experiment 1). The development of I-cell embryos were more promoted in the complex medinm(Ham's Fl0) than in the simple one(m-KRB), but that of 2-cell embryos showed the reverse effect. The bovine serum albumin(BSA) as a medium snpplement more promoted the development of I- and 2-cell embryos, compared with human fetal cord serum(HCS). On the other hand, the harmful effect of HCS was especially shown on the early cleavage in the embryonic development of the two stages. The effect of serum, in the respect of interaction between media and snpplements. was also more significantly appeared in m-KRB than Ham's Fl0. In the experiment 2, when the harmful effect of HCS was compared with that of fetal bovine serum(FBS), the former more promoted the development of l - and 2-cell embryos than the latter. The effect of HCS was more significantly shown in the development of I-cell than that of 2-cell embryos. Conclusively, as I- and 2-cell embryos were different in the requirements for the in vitro development. the optimal medium and supplement have to be selected for each embryonic stage. It is also respected to the better result if it take into consideration into the kinds of sera when serum is used for culture of early preimplantation embryos.
