Knowledge of molecular mechanisms underlying gustatory transduction has recently enjoyed significant advances, largely due to using animal models. However, the wide diversity in taste sensitivity and specificity among mammals warrants studies in human tissue. We describe a biopsy technique to collect living taste cells from the papillae on human tongue.

The Tongue and Taste Buds

The surface of the tongue is covered with various small bumps called papillae, which either distribute what has been ingested (filiform papillae) or contain the sensory taste (or gustatory) receptor cells (fungiform, circumvallate, and foliate papillae). Embedded within each taste-related papilla are the taste buds—clusters of 30 to 100 gustatory receptor cells. Gustatory receptor cells extend finger-like projections called gustatory hairs (or microvilli) into a region known as the taste pore.

We aimed to develop a reproducible protocol for isolating and maintaining long-term cultures of human fungiform taste papillae cells. Cells from human fungiform papillae obtained by biopsy were successfully maintained in culture for more than eight passages (12 months) without loss of viability.

The human tongue is a fascinating and complex organ, responsible for various essential functions such as swallowing, speech, and taste. It is also subject to various conditions and diseases. In this article, we delve into the anatomy of the tongue, its roles, and some common conditions that can affect it. Anatomical Position in the Oral Cavity The tongue is located within the oral cavity, also known as the mouth. It is attached to the floor of the mouth by a fold of mucous membrane called the...

FAQs
The diagram suggests that each basic taste has an exclusive tongue region, but taste receptor cells are distributed across taste buds throughout the tongue and other oral tissues. Because the same oral surfaces can participate in detecting multiple taste qualities, regional testing should not be interpreted as evidence for sharply separated sweet, salty, sour, or bitter zones.
Specialized molecular sensors in taste receptor cells respond to sweet, salty, sour, bitter, and umami stimuli. Those cells then transmit information through sensory nerves to the brain, where the signals contribute to taste perception. This pathway explains why the location of stimulation alone cannot account for the complete sensory experience.
Umami is one of the taste qualities detected by specialized molecular sensors, alongside sweet, salty, sour, and bitter. Its inclusion shows why a four-category regional diagram is incomplete: the biology of taste depends on receptor mechanisms and neural signaling rather than assigning each sensation to one tongue location.
Students should treat regional differences in reported sensation cautiously rather than using them to confirm exclusive taste zones. Since receptor cells occur throughout the tongue and other oral tissues, an experiment should be interpreted in relation to distributed detection and sensory nerve signaling. This approach helps prevent the traditional diagram from biasing conclusions.
Taste refers to signals produced by oral taste receptors, whereas flavor also depends on smell and other oral sensations. A person’s complete food experience therefore cannot be explained by tongue receptors alone. Making this distinction helps students interpret sensory observations more accurately and prevents flavor changes from being attributed only to taste biology.
A more accurate model of taste supports research on nutrition, appetite, medicine, and disorders affecting taste perception. Understanding distributed receptors and neural signaling helps connect changes in sensory experience with broader biological questions. It also gives researchers and students a sounder basis for interpreting experiments involving taste responses and altered perception.
