Advances in the treatment of dental stem cells for Parkinson′s disease

Parkinson′s disease (PD) is the second most common neurodegenerative disease, mainly due to the loss of dopaminergic neurons in the substantia nigra (SN) of the midbrain, resulting in motor dysfunction. Dental stem cells (DSCs) are derived from the cranial neural crest which can be easily harvested. DSCs coming from the cranial neural crest have excellent proliferation and differentiation ability, and can promote nerve repair and regeneration. DSCs can secrete new dopamine neurons and secrete a large number of neurotrophic factors(NTFs) to improve the neural function, and also inhibit the neuroinflammatory response through immune modulation. DSCs can effectively alleviate the motor dysfunction in rats with PD and play an important role in R&D of regenerative medicine.
