Abstract: The songbird forebrain continues to generate neurons in adulthood, from precursor cells located in the ependymal/subependymal zone (SZ) over the mediocaudal neostriatum. Precursor mitosis is followed by migration of neuronal daughter cells into the underlying forebrain, along radial fibers derived from the SZ. To define the ontogeny of both the new neurons and their radial guide cells, we employed retroviral insertion of the lacZ gene into neostriatal SZ precursor cells derived from postnatal and adult songbirds. We found that single SZ cells generate both neurons and substrate glia in vitro, and in an analogous fashion, both neurons and radial cells in vivo. This suggests that newly generated neurons and radial cells of the adult avian brain derive from a common pluripotential progenitor.
