Supplementary Figure 11: Expression of Gsx2, Pax6 and Sp8 in E55 monkey forebrain.
From: Subcortical origins of human and monkey neocortical interneurons
(a–f) Gsx2 and Sp8 double-immunostaining was performed on E55 monkey brain sections. (g–j) Higher magnification of boxed areas in (a, c, f). Gsx2 was mainly expressed in the GE VZ, while Sp8 was mainly expressed in the LGE/CGE SVZ. Many Gsx2+/Sp8+ cells were found in the SVZ. (k–p) Pax6 and Sp8 double-immunostaining was performed on E55 monkey brain sections. (q–t) Higher magnification of boxed areas in (l–n). Note that all Sp8+ cells in the medial cortical VZ expressed Pax6 (i), suggesting that they are primary progenitors of excitatory glutamatergic projection neurons.
