Fig. 4From: PAK1 regulates cortical development via promoting neuronal migration and progenitor cell proliferationImpaired neuronal migration in PAK1 KO mice. a, b Pregnant mice were injected with BrdU at E14.5 and the brains of the WT (a) and PAK1 KO littermates (b) were dissected at P7 and stained with anti-BrdU antibodies. c Summary graph showing a significant shift of migrating cells to the deep layers of the cortex in PAK1 KO mice. *p < 0.05, ***p < 0.001Back to article page
