Safer Way Found to Make Stem Cells From Skin

Scientists have found a safer way to make stem cells from ordinary human skin cells, a discovery that could render obsolete the debate on using embryonic cells for research on Parkinson's, diabetes, cancer and spinal injury treatments, Reuters reports. The new technique uses a DNA thread instead of a virus—which can cause mutations, even cancer—to inject the cell-reprogramming genes.
