Whitehead Institute researchers have greatly simplified the creation of so-called induced pluripotent stem (iPS) cells, cutting the number of viruses used in the reprogramming process from four to one. Scientists hope that these embryonic stem-cell-like cells could eventually be used to treat such ailments as Parkinson's disease and diabetes. The earliest reprogramming efforts relied on four separate viruses to transfer genes into the cells' DNA, one virus for each reprogramming gene. (source: wi.mit.edu)
