A New Benchmark for De-Aging Comes From Slowly Turning Back Cells’ Clocks
Scientists have long known how to make cells younger—at least in the sense that adult cells can be converted into pluripotent stem cells very similar to those found in embryos. While this capability has been foundational for biological research, these methods aren’t viable for anti-aging technologies, for a few reasons.
“You don't want to have a pluripotent cell in your body, because it can become all types of cells,” says Oliver Brüstle, a professor who studies stem cells at Germany’s Bonn University.
Additionally, the few key genes involved in the stem cell conversion process can drive the formation of cancer if left active. That’s why Brüstle and his team have looked for other ways of de-aging cells without going through a pluripotent state. In their recent study published in Aging Cell, the researchers started with blood cells from people of various ages, including an infant and a 101-year-old...
