Outline of Final Research Achievements |
We identified a transcriptional co-repressor that is important for maintaining undifferentiated state of human pluripotent stem cells by genetic screening, and investigated the molecular mechanism of its function through chromatin binding analysis and comprehensive gene expression analysis of the knockout of the co-repressor. Our data revealed that the co-repressor forms a complex with PRDM14, a known transcriptional regulator required for the maintenance of undifferentiated state of human pluripotent stem cells, and that they cooperate in the regulation of gene expression.

Academic Significance and Societal Importance of the Research Achievements |
ヒト多能性幹細胞は基礎研究から臨床応用まで幅広く利用される重要な細胞であるが、その未分化性を制御する分子機構は完全に理解されておらず、そのことがヒト多能性幹細胞の質的な不均一性とも結びついている。未分化維持に重要な新たな因子とその制御機構を見出した本研究成果は、遺伝子発現の制御に関わる複雑な調節機構の理解へと一歩近づけるものであり、基礎・応用の両面でのヒト多能性幹細胞の将来的な利用をさらに促進するものとなることが期待される。
