Interesting stuff..probably to late for most of us geezers..bur for our grandchildren..they may live a long time!
Aging Is Reversible—at Least in Human Cells and Live Mice - Scientific American - Pocket
Matt Kaeberlein, a molecular biologist at the University of Washington who studies aging but was not part of the work, says other researchers have found that the Yamanaka factors can rejuvenate cells—so in some ways this study is not surprising. But Kaeberlein says no one else had yet shown that the factors can treat age-related diseases in an animal by making the same changes. “That’s the wow factor,” he explains.
Kaeberlein says the study suggests it may be possible not just to slow aging but to actually reverse it. “That’s really exciting—that means that even in elderly people it may be possible to restore youthful function,” he says. Plus, it is easier to imagine a treatment that makes changes to the epigenome than to consider going into every cell and changing its genes. He also notes that the results of the new study are very similar to those seen when senescent cells—those that have lost function due to aging—are removed from an organism. It is not yet clear, he says, whether “this is another way to shut down or maybe reprogram senescent cells.”
