Histological analysis of the cerebral cortex at P0 in Itga3-null mice. a–d, Overall brain morphology and the organization of the cerebral cortex appeared unaltered when analyzed by Nissl staining. e, f, Cell density in layers V/VI and cortical thickness (at similar anatomical levels as shown in Fig. 4
d) was not significantly altered in Itga3-null mice. Scale bars: a, b, 425 μm; c, d, 690 μm.
