Giving old mice young blood reversed age-related declines in brain function, muscle strength and stamina... researchers say
Researchers in the US are closing in on a therapy that could reverse harmful ageing processes in the brain, muscles, heart and other organs. Hopes have been raised by three separate reports released by major journals on Sunday that demonstrate in experiments on mice the dramatic rejuvenating effects of chemicals found naturally in young blood.
Infusions of young blood reversed age-related declines in memory and learning, brain function, muscle strength and stamina, researchers found. In two of the reports, scientists identified a single chemical in blood that appears to reverse some of the damage caused by ageing.
Doug Melton, a stem cell scientist at Harvard, said: "This should give us all hope for a healthier future. We all wonder why we were stronger and mentally more agile when young. There seems to be little question that, at least in animals, GDF11 has an amazing capacity to restore ageing muscle and brain function.
