Abstract

Glial progenitors colonize the CNS widely in the perinatal period, but the pathways and mechanisms of migration are not well understood. We investigated the migration of progenitors from the neonatal rat forebrain subventricular zone (SVZ) by labeling them in vivo with a retrovirus encoding green fluorescent protein and visualizing movements by time lapse microscopy in slices. Cells within the dorsolateral SVZ moved in an undirected fashion but migrated radially and tangentially after emigration into white matter, cortex, and striatum. Cells in the striatal SVZ migrated parallel to the ventricular surface. During migration, elongation of the leading process and nuclear translocation were independent or linked. Orthogonal turning involved either cessation of cell body movement and formation of a new leading process or continuous cell body movement and bending of the leading process.
