Somewhat surprising results, though. They took a fraction of pig blood plasma and injected it into rats over the course of 8 days. Some organs in the older rats showed a lower epigenetic age, and the older rats also performed quicker in cognitive tests. The results are more extreme than they predicted they be (especially the liver and heart), so we’ll see what happens when someone tries to replicate the results.
Any speculation about applicability to humans is just science fiction, of course.
“Reverses aging in rats”. We’ve also cured cancer in mice dozens of times without the results generalizing to human beings. So even if this works, it may only work on rodents.
Let’s just hope the rats don’t figure out how to do it for themselves, or we’ll be overrun with rejuvenated geriatric rodents.
