A Review of Efforts to Develop Stem Cell Therapies for Neurodegenerative Conditions
Narrative review summarizes experimental and clinical evidence for stem cell therapies across Parkinson's, Alzheimer's, ALS, and Huntington's. It highlights diverse cell types and delivery methods, widespread unregulated clinic use, inconsistent trial outcomes, and regulatory and ethical challenges.
Why it mattersParkinson's and Alzheimer's stem‑cell trials show inconsistent results; require randomized trials and clear IP/regulatory plans before investment.
