Stem cells have been suggested as candidate therapeutic tools for neurodegenerative
disorders, given their ability to give rise to the appropriate cell types after grafting in vivo. In
this review I summarize some of the evidence currently available concerning two
approaches for the treatment of Parkinson's disease:(1) The generation of dopaminergic
neurons from embryonic stem cells, multipotent stem cells, and neuronal progenitor cells for
cell replacement therapy.(2) The engineering of multipotent stem cells to release glial cell …
