In Japan, a new therapy for severe heart failure using skeletal myocardial sheet is ongoing and a treatment using iPS cells is just about to start. However, I think there are problems and concerns. In this comment, I will express concerns on these treatments. This will be useful and interesting to stem cell researchers and clinical cardiologists.
