Outline of Final Research Achievements

We have approached the development of new technologies that can be used to create a three-dimensional bioartificial heart with functions and morphology comparable to living organs:
# 1. We have developed a new decellularization technology using surfactants and glycolipid substances; # 2. We reported a method for promoting maturation and self-organization of human iPS cell-derived cardiomyocytes; # 3. We investigated the relationship between stress fibers (actin) and YAP signals. The result suggests that YAP signals also play an important role in self-organization; # 4. We have established a three-dimensional cardiac imaging technique that can be used for organ-like three-dimensional myocardial tissue by applying the tissue- clearing technique (CIBIC-2).

Academic Significance and Societal Importance of the Research Achievements

心臓全体がびまん性広範囲に障害を受け、重篤な機能不全に陥っている心筋症のような病態に対しては、ドナーからの臓器移植を含む治療が行われているが、臓器そのものを再生し、移植する方法の開発が期待されている。近年、脱細胞化細胞外マトリックスを用いて立体臓器を構築する方法が一定の効果を示し、注目が集まるようになったが、生体臓器に匹敵するバイオ人工心臓を構築するには様々な課題を解決する必要があり、細胞が本来あるべき場所に生着し、生着、成長する、自己組織化を理解することが不可欠である。本課題により、三次元心筋組織構築に有用な知見が得られた。
