Supplementary Figure 15: Ascl1 expression in GW24 human neocortical and subcortical progenitor cells.
From: Subcortical origins of human and monkey neocortical interneurons

(a) Immunostaining for Ascl1 in GW24 human coronal brain section. (b–e) Higher magnification of boxed areas in (a) showing Ascl1+ cells in the neocortical SVZ (b), LGE (c), MGE (d), and ventral PSB (e). (f–h) Higher magnification of the boxed area in (b) showing that the majority of Ascl1+ cells expressed Pax6, suggesting that Ascl1+ cells in the neocortical SVZ are progenitors of neocortical projection neurons. Scale bars, 1 mm (a), 400 μm (b–e); 100 μm (f–h).
