F35 mice co-expressing N-terminal deletion mutants are normal at 3 weeks.

<p>Animals of the indicated genotypes were sacrificed at 3 weeks and brain sections were stained with hematoxylin and eosin. Images show the whole cerebellum (A–F), the granule cell layer of the second cerebellar lobe (G–L), and the cerebellar white matter (M–R). Scale bars = 1 mm (A–F) and 100 µm (G–R).
