Cell replacement therapy in Parkinson’s disease

barrow, tom, robert;

With an ageing population, the incidence of Parkinson’s disease is increasing. The disease has an overwhelming impact on those it affects and has a limited repertoire of drug therapies available, each with problematic side effects. Stem cell therapy is an exciting prospect in the treatment of several neurodegenerative conditions. This article takes an in depth look at the great potential of cell replacement therapy for Parkinson’s disease, providing supporting evidence for investment in this potential treatment. After considering the basis for cell replacement therapy, the article looks at stem cells of different origins, summing up the strengths and limitations of each in relation to Parkinson’s disease. In addition to highlighting the cell replacement therapies available, the article also provides a chronology of research into this emerging field over the last 30 years.
