Abstract

Neuroblast migration is a major component in the process of neuronal circuit assembly. In the rodent postnatal brain, the subependymal zone (SEZ) is the largest neurogenic niche where new neurons are born throughout life. These cells migrate several millimeters following a specific pathway called the rostral migratory stream (RMS) towards the olfactory bulb. Once they reach their final destination, they differentiate mainly as interneurons and integrate into already established neuronal circuits. Along the RMS, neuroblasts use a particular mode of migration known as chain migration. They stay attached to each other while migrating and are intimately associated with adjacent astrocytic processes. To dissect the molecular and cellular signals involved in neuroblast migration, we developed an in vitro system consisting of SEZ-derived explants co-cultured on top of an astrocyte monolayer.
