title: Variety in histochemical characteristics of the olfactory receptor cells in a flatfish, barfin flounder (Verasper moseri).
abstract: Variety in histochemical characteristics of the olfactory receptor cells (ORC) was examined by immunohistochemistry for protein gene product 9.5 (PGP9.5) and calretinin, and by lectin histochemistry with Phaseolus vulgaris leucoagglutinin (PHA-L) in the olfactory epithelium (OE) of the barfin flounder (Verasper moseri). PGP 9.5 immunoreactivity was observed in the ORC situated in the upper three fourths of the OE. Calretinin immunoreactivity was observed in the ORC which seemed to be immunonegative for PGP 9.5. These cells were located in the upper two thirds of the OE. PHA-L staining was observed in small subsets of the ORC. PGP 9.5 and calretinin immunoreactivities and PHA-L staining were also observed in the crypt cells unique to the fish OE. These findings suggest the different properties of olfactory perception among fish ORC.
