| Research Abstract |
Implantation is critical for the embryonic development in mammals. This study aimed to understand the dynamic change of the epigenetic status during implantation. Analyses of histone modifications and global gene expression in mouse pre-and post-implantation embryos successfully revealed the epigenetic dynamics during implantation. Specifically, we found that H3K9me2, suppressive histone modification, dramatically decreases during implantation and this decrease seems to normalize the epigenetic abnormities in cloned mice generated by somatic cell nuclear transfer.
