title: Ontogeny of electrically excitable cells in cultured olfactory epithelium.
abstract: A primary system has been developed in which it is possible to study the production of electrically excitable neuron-like cells from a precursor population of olfactory epithelial cells. Rat nasal epithelium was dissociated and placed in culture. The initial surviving cells are flat and ciliated and contain glial fibrillary acidic protein (GFAP). After 3-5 days electrically excitable cells appear that contain neuron-specific enolase but not GFAP. These round cells originate by means of the differentiation of the GFAP-positive flat cell to a round cell, followed by the division of the round cell. Therefore, neuron-like cells can be derived from cells that synthesize GFAP.
