CTIP2 is specifically expressed in medium spiny neurons. A–D, CTIP2 expression in MSN labeled with DARPP-32. A, Coronal section of adult striatum, showing colocalization of CTIP2 (red) with DARPP-32 labeled MSN (green). B, C, High-magnification image of DARPP-32 expression (B) and CTIP2-labeled nuclei (C) in the boxed area in A. D, Merged image of B and C, showing that all DARPP-32 labeled MSN express CTIP2. E–H, CTIP2 expression in MSN labeled with FOXP1. E, Coronal section of adult striatum, showing colocalization of CTIP2 (red) with FOXP1 labeled MSN (green). F, G, High-magnification image of FOXP1-labeled MSN (F) and CTIP2-labeled nuclei (G) in the boxed area in E. H, Merged image of F and G, showing that all FOXP1-labeled MSN express CTIP2. Fewer than 1% of CTIP2-labeled cells are FOXP1 negative (arrowhead). Arrows indicate examples of colocalization. Scale bars: A, E, 200 μm; B–D, F–H, 10 μm.
