Ask the MD: Stem Cells and Parkinson’s Disease

Understanding Stem Cells and Parkinson's Disease

Introduction to Stem Cells in Parkinson's Research

  • Dr. Rachel Dolhun introduces herself as a movement disorder specialist and discusses the role of stem cells in understanding and treating Parkinson's disease.
  • Early clinical trials are underway, with more anticipated, focusing on the application of stem cells for individuals with Parkinson's.

Types of Stem Cells

  • There are different types of stem cells: embryonic stem cells can develop into any cell type, while adult stem cells are limited to producing specific cell types (e.g., skin or blood).
  • Researchers can reprogram adult stem cells into induced pluripotent stem cells, allowing them to transform into various cell types, including brain cells.

Research Applications of Stem Cells

  • Induced pluripotent stem cells serve as both potential therapies and research tools, helping scientists understand genetic and environmental factors contributing to Parkinson’s.
  • Clinical trials must establish the safety and efficacy of these therapies before they become widely available; researchers face challenges regarding dosage and administration methods.

Current Challenges in Stem Cell Therapies

  • While ongoing clinical trials explore the use of stem cells for treating Parkinson’s symptoms, many unregulated clinics offer treatments that lack scientific validation.
  • These unverified treatments often involve taking a patient's own skin or fat cells, modifying them, and reinfusing them without proper safety evaluations.

Limitations of Stem Cell Treatments

  • If approved, stem cell therapies may primarily address movement-related symptoms like tremors but might not alleviate non-movement symptoms due to their focus on replacing dopamine-producing brain cells.

People with Parkinson’s and their families often ask about stem cells — their potential to treat disease, the state of ongoing research, and the safety of unproven stem cell therapies offered outside of clinical studies. Rachel Dolhun, MD, movement disorder specialist and vice president of medical communications at The Michael J. Fox Foundation, discusses the facts about stem cells and Parkinson’s. The "Ask the MD" series is intended as an educational resource for people with Parkinson's and their loved ones. Please consult with your personal healthcare provider to address individual medical questions. The Michael J. Fox Foundation for Parkinson's Research is dedicated to finding a cure for Parkinson's disease through an aggressively funded research agenda and to ensuring the development of improved therapies for those living with Parkinson's today. https://www.michaeljfox.org We gratefully acknowledge the Steering Committee members of our Patient Disease Education Consortium in conjunction with The Albert B.
