Single virus used to convert adult cells to embryonic stem cell-like cells
CAMBRIDGE, Mass. (Dec. 15, 2008) 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 coul...
