Living a normal life, while remaining in good health and avoid chronic diseases associated with aging. Who of us would not put his signature? And although for now there is still a dream, to take a major step in this direction were the British researchers from the universities of Exeter and Brighton, led by Lorna Harries. In fact, in their study, published in the pages of the journal BMC Cell Biology, they just put a new way to rejuvenate in the laboratory some old human cells. And not only that the treated cells have been shown to be able to behave like younger ones. In other words, a few hours after the treatment the older cells began to divide, showing longer telomeres, the ends of chromosomes that usually get shorter as we grow older. "We have observed that cells recapture some of the characteristics of youth. They are able to grow and their telomeres, which are found on the ends of chromosomes and usually get shorter with age - are longer, just like the young ones, "explains the author. "Now you need a lot more research to be able to deal with the degenerative effects of aging."
