Story summary

Researchers at the University of Southern California's Keck Medicine are testing a stem cell therapy for Parkinson's using induced pluripotent stem cells (iPSCs) to replace damaged brain cells and boost dopamine.
The therapy implants iPSC-derived cells into the brain and follows patients for up to five years.
This could help about one million Americans with Parkinson's, where no therapies slow progression.
