During cerebral cortical development, neurons and glia are produced directly or indirectly from neural stem cells in the ventricular zone and migrate to their final destinations. The behaviors of migrating neurons are well described, and several migration modes have been reported for radially migrating cells, including locomotion, somal translocation, multipolar migration, terminal translocation, and climbing mode of migration (Nadarajah, et al., 2001; Tabata and Nakajima, 2003; Tabata et al., 2009; Kitazawa et al., 2014). Using these modes of migration, neurons born near the ventricle basically move toward the brain surface.
Here, we report a novel migration mode, erratic migration. During observations of the cells migrating from the ventricular zone, we have noticed that some cells moved in a very unique manner that had not been previously described: these cells moved very rapidly and almost randomly within both the intermediate zone and the cortical plate and frequently underwent cell division. These cells frequently migrate along a scaffold of blood vessels, spreading widely throughout the cortical plate. Results of the lineage analyses both in vitro and in vivo will also be presented.
