The therapeutic possibilities offered by iPS cells seem unquestionable, and may increase with the commitment of the Japanese government to promote research using them. Indeed, according to an article in Nature Biotechnology (31; 272-273, 2013), the Japanese government are going to dedicate 222 million dollars to construct a research institute dedicated to Yamanaka, the man who set up the method for obtaining iPS cells, and who received the Nobel Prize in Medicine 2012 for this research. The institute will be designed for research on the possibility of using of these iPS cells in regenerative medicine. Moreover, the Japanese minister of science has given the green light to a financial plan that will allocate 93 million dollars annually to stem cell research. This news is unquestionably encouraging in view of the possibility of the therapeutic use of iPS cells in human medicine.
