Drebrin is highly expressed in SVZ-derived migratory neuroblasts.

<p>(A) Immunostained sagittal brain sections from P7 (left) and P90 (right) mice show strong drebrin expression (brown) in the subventricular zone (SVZ), rostral migratory stream (RMS), and olfactory bulb (OB). (B) Confocal images from P7 mice SVZ sagittal sections showing that drebrin immunostaining overlaps with DCX+ migrating neuroblasts (top row), but is almost completely excluded from GFAP+ stem cells and astrocytes (middle row). Very little colocalization is observed with Mash-1+ transit-amplifying progenitors (bottom row). Merge panels include DAPI staining to visualize cell nuclei and higher magnification insets. Scale bars: (A), 200 μm; (B), 10 μm; insets, 5 μm.
