Bitter or sweet? How taste cells decide what they want to be
from Monell Chemical Senses Center via ScienceDaily
A new study advances understanding of how stem cells on the tongue grow into the different types of mature taste cells that detect either sweet, salty, sour, bitter or umami. By identifying novel genes and molecular pathways involved in shaping a taste cell's function, these findings may someday allow scientists to treat taste disorders, characterize new taste qualities or even fine-tune taste perception to encourage healthier eating.
