Different kinds of stem cells can be engineered to secrete molecules that are known to reduce some of the symptoms of Huntington’s disease. Scientists are working to see if transplanting these cells can treat animal models of Huntington’s disease. Hopefully, this will progress to clinical trials in patients quickly.
Scientists are using stem cells from Parkinson’s disease (PD) patients to see if already-discovered drugs might be useful in treating symptoms of the disease. Another approach involves creating functional brain cells in the lab, with the hope that they might replace the cells that are damaged in PD. It’s possible that one day, cells could be transplanted into the brain of Parkinson’s patients to treat the disease.
