Four monkeys with Parkinson’s disease — and previously unable to walk due to their symptoms — improved substantially after the human nerve cells were transplanted into their brains, reducing the shaking in their limbs and leading to some regaining the ability to walk, the research team, including Kyoto University professor Jun Takahashi, said Tuesday.
