Outline of Final Research Achievements

We have developed a microfluidic channel that can be combined with commercially available culture inserts with collagen vitrigel membranes, and have succeeded in reproducing the mechanical stimulation associated with blood flow in vivo by applying a flow of culture medium to cells cultured on vitrigel membranes. The morphology of co-cultured tissues consisting of myofibers and vascular endothelial cells was confirmed to be changed by the flow of culture medium. Furthermore, we found that the flow stimulation changed functions of co-cultured tissues consisting of hepatocytes and vascular endothelial cells, such as albumin production and albumin transfer to the flow, indicating that the proposed microfluidic system is useful as a model of vascular structure.

Academic Significance and Societal Importance of the Research Achievements

薬剤開発や疾患メカニズムの解明に主に用いられる動物実験では、ヒトと動物との種差から適用可能な疾患や組織に限りがあった。一方、ヒト細胞を用いた実験では、異種の細胞間の相互作用の再現が困難であり、細胞間相互作用に基づく物質移行性を評価できなかった。本研究で実現したマイクロ流路システムは、異種の共培養組織を有する血管構造モデルの創出を可能にするだけでなく、模擬血流にともなう細胞の形態や機能の再現も可能であることも示している。よって、本技術は体外での薬剤効能評価や病態解析においてパラダイムシフトを生み出す意義深い成果であると考えている。
