Micrograph of coronal sections of E17 mouse cerebral cortices electroporated at E14 co-electroporated with mCherry and HA-Cstb expressing vector, analyzed 3 dpe. Immunostaining with RFP to identify electroporated cells and GFP to identify migrating interneurons in the GAD67-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 comparing electroporated sides with the contralateral ones in the same section to avoid different distribution of interneurons rostro-caudally.
