Fig. 5. In situ hybridization analysis of Mitf target genes in or^J mutants. (A-C) Sections through E17.5 or^J/+ heterozygous or or^J/or^J homozygous littermates, as indicated, were analyzed for the following RNAs: (A) Trpm1, (B) Dct, (C) Tyrosinase. Full expression patterns are discussed in Results and summarized in Fig. 4. Note scale bar differences between or^J/+ and or^J/or^J sections. All scale bars are 100 µm.
