Micrograph of coronal sections of E17 mouse cerebral cortices electroporated at E14 co-electroporated with mCherry expressing vector and HA-empty vector or -Cstb, and analyzed 3 dpe. Immunostaining with RFP to identify electroporated cells and GFP to identify migrating interneurons in the GAD65-GFP transgenic mouse line. Ventricle (V) and cortical plate (CP) are indicated. The dashed lines represent the apical surface of the ventricles. Distribution of GFP+ interneurons in the 5 equal Bins of the mouse developing cortex-Bin1 corresponded to apical side and Bin5 to pial side. Ventricle (V) is indicated. The dashed lines represent the apical surface of the ventricles.
