Outline of Research at the Start

小胞による物質輸送は細胞内情報伝達の基本単位として知られており、抗がん剤や抗ウイルス剤などの薬物開発に関わる核心的な生命現象である。ナノスケールである小胞の3次元運動を理解するためには、細胞イメージから画像処理で得られた座標データを高精度で取得することが必須的である。本研究では、コンピュータービジョン基盤のイメージプロセッシン グ技術を多焦点イメージングによる細胞内小胞の3次元位置計測に導入させ、小胞の物質輸 送様式を高精度で追跡可能とするイメージデータ解析分野においての革新を目指す。

Outline of Final Research Achievements

This research aimed to acquire three-dimensional trajectory data of intracellular vesicles in living cells at the nanoscale and to elucidate their motion with high precision. In conventional studies, the positions of cells and intracellular organelles could be accurately captured using advanced imaging techniques, but there was an issue of errors occurring during the stage of calculating actual positions from the image data. With the image processing algorithm proposed in this study, the accuracy of image mapping was achieved at the nanoscale by applying linear coordinate transformation to two images obtained from the dual-focus optical system used for calculating three-dimensional coordinates, particularly. Furthermore, we developed software capable of performing such image processing and calculating the final three-dimensional coordinates at once.

Academic Significance and Societal Importance of the Research Achievements

がん細胞をはじめとする病気の原因となる細胞を外部の薬剤を利用して制御するためには、細胞内で行われる情報伝達パターンに関する知識が最も重要である。本研究では、細胞内での情報伝達を担当する小胞の運動を解析するため、小胞の3次元軌跡を高精度で得られるアルゴリズムを提案した。そのアルゴリズムによって実験者のマニュアルな操作による測定及び計算の誤差を最小限に抑え、簡単な操作でナノスケール精度の3次元座標データが得られる。したがって、本研究は薬剤開発や関連研究の基礎となる意義を持ち、細胞内での情報の伝達に関するあらゆる研究に貢献できると期待される。
