Fig. 5. Purkinje cell dendritic development is abnormal in Ccnd1−/− mice at P9.
Comparison of wild-type (A,C) and Ccnd1−/− (B,D) Purkinje cells stained with anti-calbindin antibody shows that at P9 (A,B), Ccnd1−/− Purkinje cell dendrites are abnormally oriented and stunted, but by 4 weeks (C,D) they look normal. Scale bars: 50 μm in A,B; 100 μm in C,D.
