Outline of Final Research Achievements

Organismal morphologies are often defined by extracellular matrices (ECMs) such as the vertebrate bones and the insect cuticle. To explore the roles of ECMs in morphogenesis, the present study focused on a cuticle deformation event that drives body shaping in a model insect, the fruit fly Drosophila melanogaster. I have found that a protein constituent of the cuticle induces cuticle folding, which later unfolds to enable deformation of the cuticle as a whole.

Academic Significance and Societal Importance of the Research Achievements

従来、細胞外基質は細胞から分泌されてその場に定着するだけの静的、受動的な材料とみなされがちであった。それに対して本研究では、細胞外基質を構成する分子がダイナミックにクチクラの構造をつくりだす仕組み、そしてその構造をもとにクチクラそのものがダイナミックに形を変えることで全身体型の形成を駆動することが分かった。生物の形はどのようにつくられるのか、という生物学の古典的、根源的な問いに対して新たな答えを提示する成果だと考えられる。
