Outline of Final Research Achievements

In the present study, we have elucidated the role of integrins on hematopoietic stem cell development in the zebrafish embryo. Integrins are known to regulate not only cell adhesion but also signal transduction in many tissues. In this study, we determined, for the first time, the signaling pathway that regulates hematopoietic stem cell development.

Academic Significance and Societal Importance of the Research Achievements

人工多能性幹細胞(iPS細胞)から造血幹細胞を造り出すためには、発生期における造血幹細胞の形成過程を分子レベルで解明する必要がある。ゼブラフィッシュは発生過程の細胞の動態を追跡しやすいなどの利点から発生生物学の分野で優れた実験モデルとして知られている。本研究で得られた知見は哺乳類でも共通である可能性が高く、今後、iPS細胞から造血幹細胞への分化誘導に応用できる可能性を秘めている。
