Outline of Final Research Achievements |
Adult rat hearts were decellularized with the perfusion of detergents, and then extracellular matrices were recellularized with cardiac cells from neonatal rats. We evaluated functional and morphological properties of organ-like three dimensional heart tissues using optical mapping and other methods. The results were published in an international journal of biomaterial sciences(Yasui et al. Biomaterials. 2014; IF 8.387). Furthermore, we succeeded in observing coronary vessels and sympathetic nerves of entire murine hearts using tissue-clearing techniques. The technique can be utilized to evaluate detailed morphological properties of organ-like three-dimensional heart tissues. (Yokoyama et al. Presented in AHA2016 etc. The manuscript is in review.)
