In the heated competition to produce iPS cells, the studies stagnated due to an incident of fabricated embryonic stem cells. Nevertheless in 2007, a group led by Prof. Shinya Yamanaka at Kyoto University generated pluripotent stem cells - iPS cells by transfecting genes, called Yamanaka factors, into cells. At about the same time, MIT Prof. Rudolf Jaenisch had successfully accomplished a similar result with mice.
