Blood cells from an 80-year-old wake up younger than 20

At the University of Bonn, Oliver Brüstle's team directly reprogrammed blood-cell precursors from an 80-year-old donor into neural stem cells — and watched their molecular age clocks rewind to under 20 years. Published in Aging Cell, the slow, 100-day transformation gives scientists a rare front-row seat for studying how cellular ageing might one day be slowed or undone.
