Outline of Final Research Achievements

Despite a remarkable progress in the treatment for severe heart failure such as heart transplantation and left ventricular assist device, heart failure is still a leading cause of mortality. Recently, it has become possible to make organ tissue outside the body by remarkable innovation of cell engineering technology and a spread usage of human iPSC.In this study, we made a human iPSC derived 3D myocardial tissue chip in vitro, and we could find a good drug responsiveness of the chip compared with the conventional monolayer cardiomyocytes. It suggests the utility as a drug screening system.
Next, we transplanted the human iPSC-derived three-dimensional myocardial tissue on the heart to heart failure models, and we could find the recovery of cardiac function. The implanted cardiac tissue after one month also remained in vivo, and the maturation was recognized compared with the tissue in vitro.
