Fig. 6. Loss of HRK does not rescue cerebellar Purkinje cells or granule neurons in lurcher mutant mice. Mid-sagittal cerebellar sections stained with H&E showing that the Hrk genotype (Hrk+/+, Hrk+/– or Hrk–/–) does not affect the size of the cerebellum in lurcher (lc) heterozygous (grid+/lc) animals. Bar, 1 mm.
