| Outline of Final Research Achievements |
This research aims to develop a novel approach for cardiac tissue engineering through the creation of the culture substrate which promotes the cardiac differentiation of ES/iPS cells and the selection of the differentiated target cells cultured on its surface. The culture substrate, a biohydrogel, was made from decellularized animal ventricular extracellular matrix. The research showed that stem cell differentiation can be modulated by controlling the mechanical properties of the culture substrate, and the target cell selection can be realized by imposing dynamic stress on the substrate. Bioreactor with mechanical stress control was developed to create the intermediate module for the cardiac tissue construction. This research presents a promising approach to tissue-engineer the highly functional cardiac tissue equivalent.
