No branch of science has grown more rapidly or produced more dramatic results than biomedicine: the biggest excitement swirled around the potential for the ultimate solution for personal medicine: an unlimited supply of replacement parts cloned from the patient’s own cells.

According to Harold Varmus, a Nobel Prize winner and the former NIH director: "The development of cell lines that may produce almost every tissue of the human body is an unprecedented scientific breakthrough. It is not too unrealistic to say that this research has the potential to revolutionize the practice of medicine and improve the quality of life."
