Blood from young mice reverses aging in brain, muscles

In a trio of studies published Sunday, scientists reported that they reversed aging in the muscles and brains of old mice — simply by running the blood of young mice through their veins, the Boston Globe reports.



The papers, from two independent groups in Cambridge and California, used different approaches to begin to unravel the rejuvenating effects of young animals’ blood, in the hopes of eventually developing a therapy that could be tested in people.

Researchers at Harvard University administered a protein found in young blood to older mice, and found that treated mice could run longer on a treadmill and had more branching blood vessels in their brains than untreated mice. A group led by a University of California, San Francisco researcher identified a molecular switch in a memory center of the brain that appears to be turned on by blood from young mice.
