Epithelial differentiation and taste buds in the soft palate of the monkey,Macaca irus

A combination of light, transmission and scanning electron microscopy was employed to demonstrate the occurrence, arrangement and structure of taste buds in the oral mucosa of the soft palate of monkeys (Macaca irus). Taste buds are found in aggregates confined to 0.15 to 0.3 mm wide, round islands of keratinizing epithelium embedded in the normally non-keratinizing integument. Topography, configuration and structure of these epithelial islands and their taste buds are described, and the question of a developmental and functional interrelationship between epithelial differentiation and properties, and taste bud function is discussed.
