Fig. 5. Tangential migration to the cortex of Slit1;Slit2 double mutants. Coronal sections through the telencephalon of E14.5 embryos showing expression of GAD67 (A,B) and Lhx6 (C,D) in wild-type (A,C) and Slit1;Slit2 mutant (B,D) mice. Arrowheads point to cells migrating in the marginal and intermediate zones of the cortex. H, hippocampus; LGE, lateral ganglionic eminence; MGE, medial ganglionic eminence; NCx, neocortex; POa, preoptic area; Str, striatum. Scale bars: 500 µm.
