Expression of DOCK7 in the postnatal mouse forebrain. (A) A cartoon representation of the V-SVZ–RMS–OB pathway. (B) Coronal sections of forebrains of P10 mice at positions indicated in the cartoon in A immunostained with antibodies to DOCK7 and DCX and counterstained with DAPI. Boxed regions in III are enlarged and shown at the bottom. Bars: (top) 50 µm; (bottom) 10 µm. (C) Coronal sections of the V-SVZ region of P10 mice immunostained with antibodies to DOCK7 and GFAP, MASH1, or nestin and counterstained with DAPI. Boxed regions are enlarged and shown at the bottom. The yellow dashed line indicates the boundary region between the V-SVZ and the lateral ventricle. Bars: (top) 25 µm; (bottom) 10 µm. (D) Localization of DOCK7 in cultured V-SVZ–derived neuroblasts. Neuroblasts dissociated from V-SVZ tissue of P1–3 mice were fixed at 30 h in vitro, followed by immunostaining with indicated antibodies and counterstaining with DAPI. Bar, 10 µm.
