Doctors at Osaka University performed the world's first transplant of heart muscle cells derived from induced pluripotent stem cells (iPS cells). It is a promising treatment for many patients with heart disease. NHK worked closely with Kyoto University which generates iPS cells and Osaka University where the transplant surgery was conducted on a long-term project to record on an 8K Ultra HD camera mounted onto a microscope. For the first time in the world, the images will reveal the entire transformation process of iPS cells which can turn into any type of cell in the body.
