Scientists Claim They've Reversed Aging in Mice

"In molecular biologist David Sinclair's lab at Harvard Medical School, old mice are growing young again," reports CNN:

Using proteins that can turn an adult cell into a stem cell, Sinclair and his team have reset aging cells in mice to earlier versions of themselves. In his team's first breakthrough, published in late 2020, old mice with poor eyesight and damaged retinas could suddenly see again, with vision that at times rivaled their offspring's.

"It's a permanent reset, as far as we can tell, and we think it may be a universal process that could be applied across the body to reset our age," said Sinclair, who has spent the last 20 years studying ways to reverse the ravages of time.

"If we reverse aging, these diseases should not happen. We have the technology today to be able to go into your hundreds without worrying about getting cancer in your 70s, heart disease in your 80s and Alzheimer's in your 90s." Sinclair told an audience at Life Itself, a health and wellness event presented in partnership with CNN.


"This is the world that is coming. It's literally a question of when and for most of us, it's going to happen in our lifetimes," Sinclair told the audience.... Sinclair said his lab has reversed aging in the muscles and brains of mice and is now working on rejuvenating a mouse's entire body.
The article points out that he's building on research by Japan's Dr. Shinya Yamanaka (which in 2007 won a Nobel prize).

But one key caveat: "Studies on whether the genetic intervention that revitalized mice will do the same for people are in early stages, Sinclair said. It will be years before human trials are finished, analyzed and, if safe and successful, scaled to the mass needed for a federal stamp of approval."
