| Outline of Final Research Achievements |
In this study, we developed a novel technique to induce angiogenesis in 3D cell sheet tissue and promote angiogenesis to connect with a host blood vessel. By introducing VEGF-encoding messenger RNA (mRNA) into the 3D cell sheet tissue and allowing it to act like a paracline in the vicinity of vascular endothelial cells, it was suggested to induce angiogenesis inside the 3D cell sheet tissue. It was also found that transplantable liver / cardiomyocyte sheets that rapidly secrete VEGF can be prepared by mRNA delivery. Furthermore, by stacking these, it can be expected to be applied to the construction of a functional three-dimensional tissue having a capillary-like structure of endothelial cells.

| Academic Significance and Societal Importance of the Research Achievements |
mRNAを利用した脈管形成と同様の内容はこれまでに報告されていない。また、移植可能な3D組織の構築が実現されれば、これまでに不可能であった肝組織の効率的な移植方法につながり、組織再生治療分野における大きなブレークスルーとなると同時に、肝組織再生治療の臨床応用への展開が期待される。
