Brain sections of the (A and B) cortex, (C and D) pons, and (E and F) brainstem in (A, C and E) wild-type and (B, D and F) Ink4d, Kip1 double-null mice. BrdUrd labeling is absent at P18 in the wild-type mouse brains. Ink4d, Kip1 double-null mice show prominent BrdUrd labeling in layers III and V of the (B, arrows) cortex, (D, arrows) pontine nuclei, and (F, arrows) brainstem nuclei including the inferior olive. (Insets) Enlarged fields of labeled cells. I, II, III/IV, and V, cerebral cortical layers; PN, pontine nuclei; ION, inferior olive nucleus. Bars = A–F, 200 μm; B Inset, 50 μm; D Inset, 95 μm; F Inset, 100 μm.
