A–C, VGluT2-immunopositive climbing fibre terminals (red) along the proximal dendrites of calbindin-stained Purkinje cells (green) in wild-type (A), fBZ/fBZ (B), and Wnt1Cre;fBZ/fBZ mice (C) at P21. Scale bar, 20 μm. D, extent of VGluT2 immunostaining in the molecular layer compared with the pial surface did not differ between wild-type (n= 13 cerebella), fBZ/fBZ (n= 15 cerebella), and Wnt1Cre;fBZ/fBZ (n= 9 cerebella) mice (P= 0.483 by one-way ANOVA).
