Method Primary source abstract: "[Investigators] have developed a culture system in which postnatal mouse SVZ neuronal precursors assemble into chains with ultrastructural and immunocytochemical characteristics equivalent to those in vivo but without the astrocytic sheath. Time-lapse videomicrography revealed that individual cells migrate along the chains very rapidly (approximately 122 microm/hr) in both directions."
Comments P.14 left column bottom paragraph: "After birth in the V-SVZ [Ventricular–Subventricular Zone], type A cells migrate a considerable distance (up to several mm) through a complex network of paths that converge as the RMS [rostral migratory stream] leads neuroblasts into the OB [olfactory bulb]. This journey is not only remarkable for the great distance but also for the highly directed nature of the migration. Type A cells appear to be actively guided rostrally, and very few appear to deviate from the restricted path into the OB. By themselves, type A cells are imbued with an extensive migratory capacity. In vitro, type A cells form chains of themselves and migrate at relatively high speeds of 120 µm/h (primary source)."
