title: Isolation and characterization of porcine circumvallate papillae cells.
abstract: Animal food intake is primarily controlled by appetite, which is affected by food quality, environment, and the management and status of animal health. Sensing of taste is mediated by taste receptor cells and is central to appetite. Taste receptor cells possess distinctive physiological characteristics that permit the recognition of various stimuli in foods. Thus, cultures of porcine circumvallate papillae cells provide a model for identification of the molecular and functional characteristics of taste receptor cells. In this study, we described the isolation and culture of porcine circumvallate papillae, using tissue explants and enzymatic digestion, and showed continuous viability and expression of pivotal taste marker proteins for more than 9 passages. In addition, cultured cells showed dramatic rises in intracellular calcium upon stimulation with several taste stimuli (sweet, umami, bitter, and fat). These cultures of porcine taste receptor cells provide a useful model for assessing taste preferences of pigs and may elucidate interactions between various taste stimuli.
