With an aging society such as Japan, the frequency of cardiovascular diseases (diseases affecting the heart and blood vessels) is expected to progressively increase in the future. Heart transplantation is an ultimate therapeutic modality for severe heart failure, however, the availability of hearts for transplantation is quite limited. Thus, there is a need to develop new therapies for severe heart failure to be able to treat more heart patients. Our laboratory is working on discoveries for new cardiovascular medicine through iPS cell technology-based cardiac regenerative therapy and drug discovery research, drawing on our lab head’s clinical experiences as a cardiovascular surgeon to design an experimental plan addressing clinical needs and to conduct studies using surgically established cardiovascular disease animal models. Our goal is to realize the healthy longevity of humans through the development of iPS cell-based cardiovascular medicine.
We are also actively working together with many research institutes and industry partners to advance clinical translational medicine. We are currently working to prepare clinical research studies for cardiac regenerative therapy using human iPS cells in collaboration with Kyoto University and industry partners.
