A new benchmark for de-aging comes from slowly turning back cells’ clocks

Researchers at the University of Bonn gradually reprogrammed blood cells from donors of different ages toward a younger state, without turning them into fully pluripotent stem cells. In less than two months, age-related signals in their DNA shifted, with one biomarker appearing up to 60 years younger, even when cell multiplication was greatly reduced. The team also guided cells toward a neuron-producing type, though differences in how blood cells and neurons age make that result harder to interpret, and the underlying mechanism remains unknown. Most importantly, the gradual process gives scientists a model for tracking de-aging step by step and comparing future research into age-related treatments.
