Induction of a midbrain dopaminergic phenotype in Nurr1-overexpressing
neural stem cells by type 1 astrocytes.

The implementation of neural stem cell lines as a source material for brain
tissue transplants is currently limited by the ability to induce specific
neurochemical phenotypes in these cells. Here, we show that coordinated
induction of a ventral mesencephalic dopaminergic phenotype in an
immortalized multipotent neural stem cell line can be achieved in vitro.
This process requires both the overexpression of the nuclear receptor Nurr1
and factors derived from local type 1 astrocytes. Over 80% of cells obtained
by this method demonstrate a phenotype indistinguishable from that of
endogenous dopaminergic neurons. Moreover, this procedure yields an
unlimited number of cells that can engraft in vivo and that may constitute a
useful source material for neuronal replacement in Parkinson's disease.
