The Timing of α-Gustducin Expression during Cell Renewal in Rat Vallate Taste Buds

The G protein subunita α-gustducin is expressed in a subset of light (Type II) but not in dark (Type I) cells in rat vallate taste buds. The thymidine analogue 5-bromo-2′-deoxyuridine (BrdU) is incorporated into DNA during the S-phase of the cell cycle and can be used to determine the time of origin...
