Endogenous repair mechanisms enhanced in Parkinson's disease following stem cell therapy

This mini-review highlights the innovative observation that transplanted human neural stem cells can bring about endogenous brain repair through the stimulation of multiple regenerative processes in the neurogenic area (i.e., subventricular zone [SVZ]) in an animal model of Parkinson's disease (PD). In addition, we convey that identifying anti-inflammatory cytokines, therapeutic proteomes, and neurotrophic factors within the SVZ may be essential to induce brain repair and behavioral recovery. This work opens up a new area of research for further understanding the pathology and treatment of PD. This paper is a review article.
