title: Proliferation of taste buds in the foliate and vallate papillae of postnatal hamsters.
abstract: The growth of the taste system in the hamster is considered in comparison to the postnatal development of other organ systems and the entire animal. No taste buds are present in vallate or foliate papillae of the hamster at birth, but they attain both the appearance and numbers of adult taste buds within 5 weeks of age. The most rapid increase in the number of taste buds occurs within the first 10 days of life, and this proliferation anticipates the weaning of hamsters which occurs by about three weeks of age. Foliate taste buds reach a maximal number within two months, but vallate taste buds continue to increase in number through 4 months of age. Taste bud proliferation and development occur earlier and more rapidly than in other organ systems. This early development of taste buds may protect the weanling hamster against accidental poisoning by noxious plants, and it may also reinforce the food intake which is required for normal growth.
