Description:
The discovery three years ago that adult cells could be reprogrammed to form induced pluripotent stem cells, or iPS cells, with similar properties to embryonic stem cells was a major scientific breakthrough. These cells hold enormous potential for drug development and even cell treatment processes, and this promise has garnered significant attention from researchers and the media worldwide. However, a major caveat to the eventual application of iPS cells is that until now all the methods used to generate them have mandatory the introduction of genetic material to make the transcription factors needed for reprogramming. Eventhough some research groups have recently generated iPS cells that lack genetic modifications, even the most advanced methods used genes in the form of plasmids, and thus the risk of genetic mutations caused by the introduced sequences remained
