Specificity of Cre expression in Drd2-Cre mice. Yellow fluorescent protein (YFP) immunofluorescence analyses of the mouse brains obtained from Drd2-Cre x LSL-YFP reporter mice. Low magnification for striatum (scale bar = 1 mm) and dentate gyrus (scale bar = 500 µm) as well as magnified views of the marked areas (white boxes) for striatum (scale bar = 500 µm) and dentate gyrus (scale bar = 200 µm) are shown. YFP (Cre recombinase) was mostly and robustly expressed in the striatum (S). Limited Cre expression was also seen in other areas of the brain such as the dentate gyrus (DG). Figures represent at least three different images.
