Outline of Final Research Achievements

This study investigated whether coculture of different cell types enables survival and cellular maturation through close communication. By co-culturing macrophages with cardiomyocytes and cancer cells, we found that macrophages can survive in an environment where survival is normally not possible, and that their cellular functions are significantly altered. We found that macrophages become cardiac macrophage-like when co-cultured with cardiomyocytes, and become a type of macrophage that promotes cancer growth when co-cultured with cancer cells.

Academic Significance and Societal Importance of the Research Achievements

マクロファージは組織に応じて大きく異なる機能を獲得する。本研究では、マクロファージと組織の細胞との間の密接なコミュニケーションが、マクロファージに固有の機能を付加すること、またこの時、両者の間で細胞生存についても必須の相互作用が生まれることを見いだした。がんにおいては、免疫を阻害して、がんの増殖を進めるような機能を獲得することを見いだした。本研究で得られた成果は、全く新しい治療法開発へと発展する可能性が高い。
