Outline of Final Research Achievements

Using human induced pluripotent stem cells, morphogenetic processes of dorsal tissues (backbone anlagen, spinal cord anlagen, etc) in human fetus were reproduced in vitro for the first time in the world. By studying this experimental system, some mechanisms of tissue morphogenesis in human are confirmed to be the same as in model animals. In addition, tissue morphogenesis were impeded by methylmercury, which is a poison passing through placenta, in this experimental system. These results give us clue for a human tissue morphogenesis study, and give a new assessment system for chemical toxicity.

Academic Significance and Societal Importance of the Research Achievements

これまで組織形態形成の研究はマウス等のモデル動物を用いて遂行されてきた。本研究で確立した実験系は、ヒトiPS細胞を用いて、意図した場所・方向で組織形成を再現でき、これまで研究する方法が無かったヒト組織の形成過程を調べることが出来る。この実験系はシンプルで扱いやすいので、多くの研究室に対し手軽にヒト組織の研究を試みる機会を提供する。また、病気の原因解明、化学物質の毒性評価、再生医療のための組織調製など様々な研究への応用が可能である。このように本研究成果は広範な分野の研究の発展に貢献することが期待される。
