| Outline of Final Research Achievements |
The purpose of this study was to develop the experimental system using RNA sequence and CRISPR/Cas9 to identify the maternal factors involved in the regulation of preimplantation development. First, we selected the genes which are specifically expressed in oocytes and whose encoding mRNAs are rapidly degraded after fertilization. Second, we chose 4 genes from those genes and made a deletion in them by CRISPR/Cas9. In one of these 4 genes, a deletion caused unusually tight chromatin structure in the oocytes and 1-cell stage embryos. Thus, we have developed the useful system to identify the maternal factors.
