| Research Abstract |
To identify the maternal mRNA that are involved in the differentiation during preimplantation development, I conducted RNA sequencing analysis using the oocytes and embryos. The results showed that although 70% of maternal mRNAs were degraded soon after fertilization, the rest of them survived this wave of a rapid degradation. Especially, those from 691 genes were hardly degraded during the 1-cell stage. Gene Ontology (GO) enrichment analysis revealed that these genes were enriched in the GO terms categorized into transcription.
