In a recent paper, Redmond et al. report that transplantation of human neural stem cells (hNSCs) leads to functional improvement in a primate model of severe Parkinson's disease. Importantly, their study indicates that the stem cells seem to act not only by replacement of dopaminergic cells, but also by supporting multiple endogenous repair systems.
