Lineages at the origin of adult neurogenic progenitors in the vertebrate pallium. (A) Lineages in zebrafish, generating adult RG from embryonic RG (top) and NE progenitors (bottom). (B) Lineages in the killifish, where neurogenesis in adults is ensured by a long-lasting non-glial embryonic lineage (blue) dph: days post-hatching, wph: weeks post-hatching. (C) Lineages in mouse, where distinct modes of NSC production are described in the DG (top) and SEZ (bottom) (Dirian et al., 2014; Furutachi et al., 2015; Song et al., 2018; Berg et al., 2019; Coolen et al., 2020).
