Outline of Final Research Achievements |
In spite of the importance of histone modifications such as H3K27me3 in cellular differentiation and development, the true function of individual modifications scattered throughout the genome has rarely been examined. To address this issue, we developed epigenome editing tools and modified ES cells (PRC2-switch ES cells) to study in situ H3K27me3. In addition, a novel knock-in method, termed BiPoD, was developed. BiPoD allows us to efficient biallelic knock-in in mouse ES cells.

Academic Significance and Societal Importance of the Research Achievements |
本研究はエピジェネティクスの重要な未解明問題に対する解決の手がかりを与えるものである。開発したエピゲノム編集ベクターやPRC2スイッチES細胞は分化や発生におけるH3K27me3の意義の解明に貢献することが期待される。また本研究で開発したBiPoDはES細胞のノックイン効率と特異性を劇的に改良する手法で、エピジェネティクスのみならず多様な研究を加速させるポテンシャルを持つ。
