Turning back time: Salk scientists reverse signs of ageing in mice

Scientists have successfully extended the lives of mice by systemically reprogramming their cells. After the experiment, the animal’s age was reversed and their lifespan increased from 18 to 24 weeks. This had not been directly demonstrated in a living organism. All previous efforts had ended in mice developing tumours and dying. The new study, published in the journal Cell, constitutes the first report of cellular reprogramming extending the lifespan of a live animal. Dec 15, 2016
