Neurogenic niches in the adult mammalian brain are composed of heterogeneous populations of neural stem cells. In this issue of Neuron, Codega et al. (2014) isolate quiescent neural stem cells from the adult subventricular zone and demonstrate their stem cell characteristics.
Mechanisms that guide directional migration of neuroblasts from the subventricular zone (SVZ) are not well understood. We report here that endogenous electric currents serve as a guidance cue for neuroblast migration. We identify the existence of naturally occurring electric currents (1.5±0.6 μA/cm(2), average field strength of ∼3 mV/mm) along the rostral migration path in adult mouse brain. El...
Evolutionary expansion and complexification of the primate cerebral cortex are largely linked to the emergence of the outer subventricular zone (OSVZ), a uniquely structured germinal zone that generates the expanded primate supragranular layers. The primate OSVZ departs from rodent germinal zones in that it includes a higher diversity of precursor types, inter-related in bidirectional non-hiera...
Large numbers of dying cells are found in proliferating tissues, suggesting a link between cell death and cell division. We detected and quantified dying cells during pre- and early postnatal development of the rat cerebral cortex using in situ end labeling of DNA fragmentation [terminal deoxynucleotidyl transferase-mediated dUTP-biotin nick end labeling (TUNEL)] and electron microscopy. The pr...
