Turn out the ancient wisdom of drinking and bathing in the blood of virgins had some truth to it...

Seriously though, I don't know how effective this is. What they did appeared to be flooding the tissue with "young blood" and observe the changes in epigenetics markers. These markers are basically conditional if/else depending on the environment so maybe there is something in the plasma that cause them to change. One thing that would be interesting to test is how fast for the tissues to switch back to the "old" forms once the plasma treatment stops.
