Adult mammalian [[neural stem cell]]s are unique because of their properties, such as differentiation capacity, [[self renewal]], [[quiescence]], and also because they exist in specific niches, which are the [[subventricular zone]] (SVZ) and [[subgranular zone]] (SGZ) - the [[dentate gyrus]] of the [[hippocampus]].
