Caption Atoh1trhl/Atoh1trhl (trhl/trhl) mice compared to wild-type (+/+) cerebellum morphology. Cerebellar abnormalities in H&E-stained and cresyl violet-counterstained sections through the cerebellum of a representative wild-type control (left panels) and a homozygous mutant (right panels) mouse shown under increasing magnification from 5X to 63X (n = 3 per group). Cerebella from each genotype were examined. The cerebellum in wild-type is well developed and foliated (A), but it is smooth (B) in homozygous mutant mice. The external granule layer (EGL) is indicated by the arrow in both middle panels. In (D) the EGL of the homozygous mutant mice is significantly underdeveloped as compared to (C). Under high magnification, the Purkinje cell layer (PCL), indicated by the star in both (E) and (F), appears disorganized in the mutant, with some Purkinje cells (asterisk in F) located deep in the cerebellum, where they are not normally found.
