• Doctors implant dopamine-producing stem cells in Parkinsonâ s patients In a bold new trial, doctors are implanting lab-grown stem cells into the brain to reboot dopamine production in Parkinsonâ s disease. • Parkinson’s disease is a long term neurological condition that gradually worsens over time. • More than one million people in the United States are living with the disorder, and about 90,000 new cases are diagnosed each year. • Current medications and therapies can ease symptoms, but no treatment has been proven to stop or slow the disease itself. • The condition is closely linked to a drop in dopamine levels in the brain. • Dopamine is a chemical messenger that plays a critical role in controlling movement, as well as supporting memory, mood, and other essential functions.
Article Summaries:
- A clinical trial at Keck Medicine of USC is testing whether induced pluripotent stem cells (iPSCs) can restore dopamine production in Parkinson’s disease. In the early‑phase study, neurosurgeon Brian Lee implants lab‑grown, dopamine‑producing cells into the basal ganglia of patients, aiming to replace lost neurons and halt disease progression. Participants are monitored for 12-15 months for symptom changes and side effects such as dyskinesia or infection, with plans for up to five years of follow‑up. The trial seeks to determine if this cell‑based approach can improve motor function and slow Parkinson’s progression.
