Chemist Cites Advance in Stem-Cell Field

Scientists have reprogrammed mature skin cells into an embryonic-like state by using proteins instead of genes, a key advance aimed at overcoming safety concerns in one of the hottest areas of biological research.

Now, instead of reprogramming the cell with four introduced genes, researchers have achieved the same result by inserting four proteins associated with those genes. This technique is deemed to be safer because it doesn't require genetic manipulation.
