Expression of CTIP1 and CTIP2 in adult cerebral cortex, hippocampus, and cerebellum. Coronal cryosections of adult mouse brain were probed with [35S]-labeled CTIP1 (B) and CTIP2 (C) riboprobes. (A) Bright-field image for panels B and C. (D–F) Sagittal sections of adult mouse cerebellum hybridized with CTIP1 (E) and CTIP2 (F) probes and the corresponding bright-field image (D). CA1–CA4, hippocampal subregions; cc, cerebral cortex; hi, hippocampus; dg, dentate gyrus; th, thalamus; pl, Purkinje cell layer.
