The therapeutic possibilities offered by iPS cells seem self-evident and are set to increase thanks to the Japanese government’s commitment to promoting research in this field. Indeed, according to an article in Nature Biotechnology (31; 272-273, 2013), Japan plans to build a 222 million-dollar research institute devoted to Yamanaka, the scientist who perfected the process used to obtain iPS cells. This scientist received a Nobel Prize in medicine in 2012 for his work in this field, and will study the use of these cells in regenerative medicine. In addition, the Japanese Minister of science has given the green light to a budget that will allocate 93 million dollars to stem cell research annually. This news will no doubt create new hope in the therapeutic use of iPS cells in humans.
