Differentiation of Taste Buds in Organ Culture
It is well established that the structural integrity of mammalian taste buds is dependent on an intact innervation . This is based on the following lines of evidence . Experiments in which gustatory nerves were severed resulted in degeneration of taste buds (5, 8, 9, 14, 17) . If gustatory nerves were allowed to regenerate into the areas they previously innervated, taste buds reappeared (8, 10,...
متن کاملMaintenance of rat taste buds in primary culture.
The differentiated taste bud is a complex end organ consisting of multiple cell types with various morphological, immunocytochemical and electrophysiological characteristics. Individual taste cells have a limited lifespan and are regularly replaced by a proliferative basal cell population. The specific factors contributing to the maintenance of a differentiated taste bud are largely unknown. Su...
متن کاملTemporal changes in NCAM immunoreactivity during taste cell differentiation and cell lineage relationships in taste buds.
Neural cell adhesion molecule (NCAM) is a type III cell marker in the taste buds. In order to clarify the cell type of Mash1-expressing cells in taste buds, expression of NCAM was examined in Mash1-expressing taste cells of adult mice in comparison with gustducin- and T1r3-expressing cells, using a combination of NCAM immunohistochemistry and in situ hybridization. About 98% of Mash1-expressing...
متن کاملCellular mechanisms in taste buds.
In the soft palate, tongue, pharynx and larynx surrounding the oral region, taste buds are present, allowing the sensation of taste. On the tongue surface, 3 kinds of papillae are present: fungiform, foliate, and circumvallate. Approximately 5,000 taste buds cover the surface of the human tongue, with about 30% fungiform, 30% foliate and 40% circumvallate papillae. Each taste bud comprises 4 ki...
متن کاملTaste isn't just for taste buds anymore
Taste is a discriminative sense involving specialized receptor cells of the oral cavity (taste buds) and at least two distinct families of G protein-coupled receptor molecules that detect nutritionally important substances or potential toxins. Yet the receptor mechanisms that drive taste also are utilized by numerous systems throughout the body. How and why these so-called taste receptors are u...
