Immunohistochemical examination for cytokeratin was performed in the olfactory mucosa of guinea pigs. Marked cytokeratin immunoreactivity was found in the basal cells.
Morphological examination with electronmicroscopy was performed at the same time. Abundant tonofilaments in which cytokeratin contained was found in cytoplasma and perikaryon of the basal cells.
These findings suggest that the basal cells have the characteristics of epithelial compornent. So the theory that the basal cell differentiate to the olfactory receptor cell is unacceptable for us from this immunohistochemical and electronmicroscopic examination.
