Fig. 5. Gsh2 mutants maintain expression of the RAR/RXR heterodimer in the
differentiating striatum. Rarb (A) and Rxrg (C) genes are
expressed in the differentiating striatal neurons at E16.5 (in situ
hybridization detection). Gsh2 mutants maintain expression of both
Rarb (B) and Rxrg (D); however, the domain of expression is
reduced in accordance with the reduction in size of the mutant striatum. Stm,
striatum.
