Researchers at Keck Medicine of USC are testing a new stem cell approach to restore movement in people with Parkinson's disease. They implant specially prepared stem cells into the brain to replace damaged cells and boost dopamine production.

Parkinson's disease is a long-term condition that worsens over time. It affects more than one million people in the United States, with about 90,000 new diagnoses each year. Current treatments can ease symptoms, but there is no cure or therapy to slow down the disease itself.

A key feature of Parkinson's is a drop in dopamine levels in the brain. Dopamine helps control movement, memory, mood, and other essential functions. As dopamine-producing cells are lost, the brain struggles to control movement, leading to symptoms like tremors, muscle stiffness, and slowed motion.

Researchers at Keck Medicine of USC are exploring a new strategy through an early phase clinical trial. They are testing whether specially prepared stem cells can be safely implanted into the brain to replace damaged cells and restore dopamine production.

The treatment uses a type of laboratory-created stem cell called induced pluripotent stem cells (iPSCs). These cells are created from adult cells like skin or blood cells, which are then reprogrammed to develop into many different types of cells. The researchers believe that these iPSCs can mature into dopamine-producing brain cells and offer the best chance of jump-starting the brain's dopamine production.

During the surgical procedure, a small opening is made in the skull to reach the brain. Using MRI guidance, the stem cells are carefully implanted into the basal ganglia, a brain region that controls movement. Patients are closely monitored for 12-15 months after surgery, and doctors track changes in Parkinson's symptoms and watch for potential side effects.

The ultimate goal is to pioneer a technique that can repair patients' motor function and offer them a better quality of life.

Why It Matters

This research has the potential to improve the lives of people with Parkinson's disease, which affects many Indians. A cure or effective treatment could also have broader implications for understanding and treating other neurological conditions.
