The activities of monoamine oxidase and acetylcholinesterase were histochemically examined in the chicken taste buds before and after hatching. Monoamine oxidase activity was observed in taste bud cells after 3 days of hatching, while acetylcholinesterase activity in nerve fibers underlying the taste buds after 17 days of incubation. These findings suggest that monoamine plays an important role as a transmitter from gustatory cells to nerve endings after 3 days of hatching, and that cholinergic nerve fibers were associated with the differentiation of taste bud cells before hatchingShow more [+] Less [-]
