Spatial expression patterns of odorant receptor molecules. Horizontal tissue sections of fresh-frozen nasal epithelium were hybridized with digoxigenylated riboprobes of fZOR6 (A and E), fZOR9 (B and F), fZOR8 (C and G), and fZOR5 (D and H). For orientation, compare Fig. 1. In A–D, the complete sections are depicted (cf. Fig. 1B). (Bar = 100 μm.) (E–H) Photomicrographs taken at higher magnification. (Bar = 50 μm.) Melanophores in the median raphe are visible as elongated dark stain (left edge of micrograph). Labeled cells are small, roundish, and dark.
