私達のグループは、生き物の空間パターンを司るメカニズム、特に細胞を「対称から非対称へ誘導する仕組み」と細胞の「非対称パターンを決める仕組み」を明らかにしようとしています。線虫C. elegansと哺乳動物の培養細胞をモデル系として使い、生きたままの細胞が増殖・分化して組織をつくる過程を詳しく観察することから、「細胞極性の成り立ち」を理解します。さらに、細胞と組織の非対称パターンを制御する遺伝子を同定し、その遺伝子産物・タンパク質の相互作用と細胞内ダイナミクスを調べることで、以下４つの疑問を解き明かしていきます。
1. 対称性の破れ：細胞を「対称から非対称に」誘導するシグナル
2. 非対称パターニング： 細胞の「非対称パターン」をコードする情報
3. 体細胞か生殖細胞か：「細胞運命」を二者択一する仕組み
4. 組織の恒常性：「組織構造の形成と維持」を司るメカニズム

Our group is interested in understanding the mechanical processes regulating: 1) The initiation of cell polarization and 2) The spatial patterning of cellular asymmetry. The simple model nematode system Caenorhabditis elegans provides a unique opportunity to explore such topics, as the embryos undergo de novo polarization with stereotypical spatio-temporal kinetics. We are also using cultured mammalian cells to investigate conserved cell polarity circuits. By using a multi-disciplinary approach, combining genetics, biochemistry, and modern imaging technology, our group aims to understand:
1. The nature of the cue(s) that initiate cell polarization
2. The mechanics of spatial patterning of cellular asymmetry
3. The role of polarity kinases in the germ-soma dichotomy
4. The mechanisms underlying tissue homeostasis

私達は特に、蛍光共焦点顕微鏡を使った高速高解像度イメージング技術を用いて、生体・細胞・分子の振る舞いを観察することで、生命現象の秘密を自分の眼で確かめることを戦略基盤とします。最先端の顕微鏡イメージングと画像解析技術が導く生命の美しさをご覧ください。
In order to delve into the mysteries in living systems, we develop new types of confocal fluorescence microscopies and image behaviours of molecules, cells, and tissues in living animals. See the beauty in microtubules, actin filaments, and regulators of cellular asymmetry in live cells.
