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

Scientists have successfully converted blood cells from an 80-year-old donor into stem cells with a molecular age of under 20. The study, published in the journal Aging Cell, used a technique called cellular reprogramming to convert the blood cells into induced pluripotent stem cells (iPSCs). The resulting iPSCs had a molecular age of around 19 years, which is significantly younger than the donor's chronological age. This breakthrough could have important implications for regenerative medicine and the study of aging.
