Scientists Edited Mice Brains So That They Live Longer — And Humans Could Be Next

Scientists edited mice brains so that they live longer — and humans could be next

In the future, scientists may edit our brains to help us live longer.

Researchers managed to successfully manipulate the lifespan of mice by adjusting their brain’s supply of hypothalamic neural stem cells, which they thought might regulate aging.

These neural stem cells create replacements for dead or damaged cells, but for mice, they begin vanishing around 10 months after birth — which is a typical mouse’s middle age, believe it or not. By the time mice turn the elderly age of 2, the stem cells are often nowhere to be found.

“By replenishing these stem cells or the molecules they produce, it’s possible to slow and even reverse various aspects of aging throughout the body,” Dongsheng Cai, a molecular pharmacologist at the Albert Einstein College of Medicine, said in a release. Read more (7/27/17)
