Blood cells from 80-year-old donor become stem cells with molecular age under 20

Researchers from the University Hospital of Bonn and the University of Bonn have succeeded in dramatically rejuvenating human cells in a test tube. They directly reprogrammed red blood cell precursors into stem cells from which neurons can be derived, resetting the molecular clocks that indicate a cell's age. This includes blood cells from an 80-year-old donor, which were transformed to have a molecular age under 20.
