A process of surgically joining the circulatory systems of a young and old mouse slows the aging process at the cellular level and lengthens the lifespan of the older animal by up to 10%.
Published in the journal Nature Aging, a study led by researchers at Duke University Medical Center in Durham, North Carolina, found that the longer the animals shared circulation, the longer the anti-aging benefits lasted once the two were no longer connected.
The findings suggest that the young benefit from a cocktail of components and chemicals in their blood that contributes to vitality, and these factors could potentially be isolated as therapies to speed healing, rejuvenate the body, and add years to an older individual’s life.
