"Scientists have turned adult cells back to their embryonic form in under 30 minutes by simply treating them with acid in a breakthough which could revolutionise personalised medicine"-- this from the sub-head of the article by Sarah Knapton in London's Daily Telegraph.
This has so far only been done with the cells of mice. But there seems to be no reason why it should not work equally well with human cells. And if it does? Well, one possibility is using those stem cells as the basis for skin grafts. Or in regenerating organs (which is already being done by other methodologies.)
Here's a link to other blog posts here on human stem cells.
Also apropos this, my recent post on " "Vampire therapy" experiments on using transfusions of fresh young blood to rejuvenate oldsters. (These "oldsters" are mice. But maybe before long . . . who knows?)
And another related link on experiments in Sweden on "rejuvenating the blood of mice by reversing, or reprogramming, the stem cells that produce blood." This from the Kurzweil Accelerating Intelligence News.
