Studies for iPS (induced Pluripotent Stem) cells are so important field for both basic science and regenerative medicine that they have attracted a great deal of attention and expectation from scientists, media and public. We revealed that unlike scientists, media and public had not paid attention to mouse iPS cell, the first achievement of the research, however, they were enthusiastic about human iPS cell. Our results suggest that the area of interest about iPS cells differed among scientists, media and public.
