For patients with brain cancer, radiation is a potentially life-saving treatment, but it can also cause considerable and even permanent injury to the brain. Now, through preclinical experiments conducted in rats, researchers have developed a method to turn human stem cells into cells that are instructed to repair damage in the brain. Rats treated with the human cells regained cognitive and motor functions that were lost after brain irradiation.
