I think this is already known.

The telomeres of younger mice (& ppl) have stem cell lines which allow for many more cell divisions than older mammals. Thus, adult stem cells have a pre-programmed senescence.

Therefore, if you want to make someone younger, you need to re-activate the telomerase gene to increase the telomere lengths of the cells in question. Probably, in this case, the in vivo environment/media of younger animals have telomerase enhancing feedback loops.

Two studies published on Sunday assert that the blood of young mice “reverses aging in old mice, rejuvenating their muscles and brains.” Vampirism and immortality are one step closer to being actually, scientifically linked. It’s like a horror film but way worse, because isn’t real life actually the scariest horror show of all?

Well, that explains Dick Cheney.

I read that trying this just led to cells going out of control like cancers, organ failures, and the subject continued to age. Putting the safety caps back on chromosomes alone doesn't appear to be the answer to aging. One thing is sure: cancer must be soundly defeated before anti-age technology can progress.
