Stem Cell Applications in Parkinsonâs Disease

Parkinson’s disease (PD), characterized by the loss of dopaminergic neurons in the substantia nigra, is one of the most common neurodegenerative disorders in elderly people. However, few effective therapies are available for neurodegenerative diseases, including PD. Stem cell therapies have been studied as potentially effective treatment options for neurodegenerative diseases through mechanisms of neuronal regeneration and substitution. Stem cells can migrate into injured regions and produce new neurons and glia, as well as neuroprotective molecules to improve neuron survival in the region. The survival and integration of these transplanted stem cells is an important issue for the success of stem cell therapy in neurodegenerative disease. Recent research in animals shows the promise of stem cell transplantation as a powerful treatment for Parkinson’s disease, among other neurodegenerative diseases, in the near future.
