Neurogenesis in dentate subgranular zone and rostral subventricular zone after focal cerebral ischemia in the rat BrdU NeuN Neural stem cells arise in the ventricles (dark blue)&the hippocmopus Merge (light blue).They give rise to other stem cells neural precursors. that give rise to neurons or glial support cells as astrocytes oligo. dendrocytes.The stem cell must migrate to differentiate only 50%do.the others dying.
