, Prof David Sinclair, a leading expert on ageing at Harvard medical school, said if the finding held up, “rejuvenation of the body may become commonplace within our lifetimes”.
Prof Steve Horvath, a senior author on the UCLA study, is now a principal investigator at Altos Labs in San Diego, which is not working with Yuvan. “I think the results are stunning,” he said. “Some people will criticise the results due to the low sample size. One swallow does not make a summer. But I believe the results because several complementary studies support them.” He anticipates safe and effective treatments will emerge from plasma research in the next 20 years.
If the therapy ever shows promise in humans – large trials are needed in more animals first – Katcher believes the plasma could be collected from pigs at abbatoirs. “I don’t like the idea, but it’s no more unethical than eating a meat sandwich,” he said. “When those pigs are killed they still have a lot of life in them. We just use that extra life instead of throwing it away.”
Prof Joao Pedro de Magalhaes, a molecular biogerontologist at the University of Birmingham, said young blood plasma was a “promising intervention”, but that he was yet to be persuaded that it can rejuvenate older animals or even delay ageing. “It’s very important we don’t confuse short-term benefits with rejuvenation,” he said.
Stop messing with animals.
