マイクロ流体デバイス上に、生体の臓器や組織の構造・機能を模倣した微小なモデルを構築する技術です。細胞を流路内に配置し、栄養や酸素の供給、機械的刺激（流れ、圧力、伸展など）を加えることで、生体内に近い微小環境を再現できます。従来の2次元培養や動物モデルでは難しかったヒト特異的な応答を、よりリアルに評価できるため、再生医療や創薬分野における革新的なプラットフォームとして注目されています。

This technology involves constructing microscopic models on microfluidic devices that mimic the structure and function of biological organs and tissues. By placing cells within the fluidic channels and supplying nutrients and oxygen while applying mechanical stimuli (such as flow, pressure, and stretching), it is possible to recreate a microenvironment that closely resembles that found within the living body. Because it allows for a more realistic evaluation of human-specific responses—which was difficult with conventional two-dimensional culture or animal models—it is attracting attention as an innovative platform in the fields of regenerative medicine and drug discovery.
