In a striking demonstration of cellular reprogramming, scientists transformed blood cells taken from an elderly donor into neural stem cells whose epigenetic markers indicated a molecular age under 20 years. The process reversed the majority of age-related changes over a period of approximately 50 days.The achievement provides a powerful tool for studying the mechanisms of ageing and cellular rejuvenation. It also raises the longer-term possibility of generating younger, patient-matched cells for regenerative therapies.While the work remains at the laboratory stage, it contributes to a growing body of research exploring how epigenetic clocks can be reset. Further studies will be needed to assess the stability and functional potential of the rejuvenated cells.The results open new avenues for investigating age-related disease and the fundamental biology of cellular ageing.
Scientists Reverse Cellular Age of Blood Cells into Youthful Neural Stem Cells
Researchers have converted blood cells from an 80-year-old donor into neural stem cells that display a molecular age of less than 20 years, effectively reversing more than six decades of cellular ageing in the laboratory.
