              number of their neurogenic divisions. Recent studies have
              revealed a new class of radial glia-like (oRG) progenitor cells
              in the human brain, which reside in the outer subventricular
              zone. Expansion of the subventricular zone and appearance of oRG
              cells may have been essential evolutionary steps leading from
              lissencephalic to gyrencephalic neocortex. Here we show that
              oRG-like progenitor cells are present in the mouse embryonic
              neocortex. They arise from asymmetric divisions of radial glia
              and undergo self-renewing asymmetric divisions to generate
              neurons. Moreover, mouse oRG cells undergo mitotic somal
              translocation whereby centrosome movement into the basal process
              during interphase precedes nuclear translocation. Our finding of
              oRG cells in the developing rodent brain fills a gap in our
              understanding of neocortical expansion.",
