Didn't the exact same team who first discovered this later realize that they had similar (if not better) effects by simply diluting the subject(=mice)'s blood with a saline/albumin mixture?
If I recall correctly it was simply a matter of removing a buildup of waste in the blood that the body had lost the ability to remove itself.
- Turing_Machine 5y agoYes, more recent work indicates that just replacing the old blood plasma is enough to show the effect. See: https://www.aging-us.com/article/103418 https://www.aging-us.com/article/103418 (kudos to this journal for not being behind a paywall!) So, as you suggest, it now appears to be more a matter of "bad stuff" being in old blood rather than "good stuff" being in young blood. Apparently there is bad stuff that the kidneys, liver, etc. just cannot remove from the bloodstream, and this bad stuff builds up over time. I suppose one analogy might be that no matter how good your oil filter is, your car still needs an oil change once in a while.
