Grafting neurons grown from monkeys’ own cells into their brains relieved the debilitating movement and depression symptoms associated with Parkinson’s disease, researchers at the University of Wisconsin-Madison report, in In the study, the UW team describes its success with neurons made from induced pluripotent stem cells from the monkeys’ own bodies. This approach avoided complications with the primates’ immune systems and takes an important step toward a treatment for millions of human Parkinson’s patients. “This result in primates is extremely powerful, particularly for translating our discoveries to the clinic.” — UW-Madison neuroscientist Su-Chun Zhang, whose Waisman Center lab grew the brain cells
