Recent advances in cerebellar granule cell migration.
In the developing brain, postmitotic neurons exhibit dynamic changes in mode, direction, tempo and rate of migration as they traverse different cortical layers. Such changes in cell migration require orchestrated activities of multiple guidance cues and transmembrane signals. In this article, we first describe when, where and how cerebellar granule cells alter their migratory behavior during the entire course of their migration. We then present how internal (inherent) programs regulate the sequential changes in the migratory behavior of granule cells in vitro. Finally, we discuss the roles of external guidance cues and transmembrane signals in controlling granule cell migration.
