Fig. 5. The striatal complex at E18.5 in Gsh1 and Gsh1/2 homozygous mutants. No abnormalities can be seen in ISL1 (A) or SOX1 (C) expression in the Gsh1 mutant striatum (Stm). The Gsh1/2 double mutant has only a rudimentary striatum as revealed by ISL1 (B) and nearly absent SOX1 (D) staining. Acc, nucleus accumbens; OT, olfactory tubercle.
