Targeted electroporation of defined lateral ventricle wallS. (A) Quantification of the percentage of GFP+ RGCs in subregions of the LV following lateral, dorsal and septal electroporation. Note the efficient targeting of distinct LV walls with different positioning of the electrodes. The most ventral regions of the lateral and septal LV walls, however, show lower numbers of electroporated cells. Error bars represent standard error of the mean. (B) Quantification of the percentage of GFP+ RGCs at defined rostro-caudal levels of the LV. (C-E) Representative overviews of the distribution of electroporated (GFP+, green) cells at two rostro-caudal levels of the LV (that is, Bregma 1.4 mm and 0.2 mm). DAPI (blue) was used as a nuclear counterstain. Scale bars: 1 mm. Ctx, cortex; EPO, electroporation; Sp, septum; Str, striatum.
