Abstract
Parkinson’s Disease (PD) is the second most common neurodegenerative disease after
Alzheimer’s disease. Though significant insights into the molecular-biochemical-cellular-behavioral
basis of PD have been understood, there is no appreciable treatment available till date. Current
therapies provide symptomatic relief without any influence on the progression of the disease. Stem
cell therapy has been vigorously explored to treat PD. In this comprehensive review, we analyze
various stem cell candidates for treating PD and discuss the possible mechanisms. We advocate the
advantage of using neural crest originated Dental Pulp Stem Cells (DPSC) due to their predisposition
towards neural differentiation and their potential to regenerate neurons far better than commonly
used bone marrow derived mesenchymal stem cells (BM-MSCs). Eventually, we highlight the
current challenges in the field and the strategies, which may be used for overcoming the impediments.
Keywords:
Parkinson’s disease, stem cells, Dental Pulp, neuroprotection, exosomes, BM-MSC.
