Abstract
The expression of mouse two-cell stage specific genes was studied using the modified DDRT-PCR method, which overcame the paucity of the experimental materials of preimplantation embryos. Embryo tissues equivalent to that of four blastomeres are sufficient for amplification of target genes as visualized using polyacrylamide gel. Sequence analyses and reverse Northern blots indicate that the genes of ATPase 6 and Ywhaz are expressed specifically in two-cell embryos. ATPase 6 is essential for one-cell to two-cell transition and plays an important role in establishment of oxidative phosphorylation, while Ywhaz is related to initiating cellular communication system.Keywords
