Distribution of transplanted MGE-derived CINs within the cortex. A, Sagittal section of host cortex showing similar dispersion of transplanted Vgat+/+, Vgat+/−, and Vgat−/− CINS. Distribution between the different layers of the cortex (B) and the distribution from the injection site along the rostrocaudal axis (C) and mediolateral axis (D) were similar in transplanted Vgat+/+, Vgat+/−, and Vgat−/− CINS. E, Cell density was also comparable between the three genotypes.
