Dracula may have been right, study finds Transfusions of younger blood give boost to older mice ↑見出し
Scientists at Stanford University found that wiring up an old mouse to the blood stream of a young one gave a major boost to muscle recovery time in the older one.
By contrast, when old blood was pumped round the body of a young mouse, muscle recovery time became more prolonged, they said in the science journal Nature. ※by contrast =それに反して
It was not just muscles that benefited. The same was true of the livers of older mice. 筋肉だけでなく、肝臓でも有効性が確認できた。
Researchers said the results suggested that the aging process lay less with the organs themselves than with the tired blood off which they fed. 老化は臓器の衰えより、循環する血液に負うところが大きいのでは?
