查询词典 discovery

At present there is no effective therapeutics to treat PD except the allopathy. The discovery of neural stem cells in the adult mammalian brain provides a new chance to effect a radical cure on PD. But how to make the limited neural stem cells proliferating enough and differentiating into the dopaminergic neurons which can repair the nigrostriatal pathway and help to eliminate the PD symptoms becomes an urgent problem.
