Outline of Final Research Achievements |
A three-dimensional culture chamber with mechanical or electrical stimulation was constructed as an intelligent culture system, enabling real-time fluorescent observation of morphology while culturing tissue. We cultured myoblast cell line C2C12 and human iPS-derived cardiomyocytes, evaluated their maturation while applying stimuli, and established an experimental cycle to improve maturation indices by extracting maturation indices by image processing and optimizing conditions by Bayesian optimization in the C2C12 and electrical stimulation system. In addition, we constructed human iPS-derived cardiomyocytes in the shape of 3D fibers and matured them by electrical stimulation and observed changes in tissue contractility when drugs were applied, indicating the possibility of applying the formed cardiomyocytes to drug testing.
