Abstract

Tongue anlage were taken in chick embryos from the 7th to the 21st d of incubation and in 3 d old chicken. A battery of 7 different horseradish peroxidase-conjugated lectins (PNA, ConA, DBA, SBA, LTA, WGA, UEA I) was used to study the carbohydrate residues of glycoconjugates at the epithelial cells of the anterior and posterior lingual glands. Some sugar residues, detected at the surface of the epithelial cells in early developmental stages of glandular primordia, seemed to play a role in inducing and regulating the first differentiative steps of the glands. Differences in type, amount, time of appearance and cellular localization between the 2 groups of glands were detected. The group of the anterior lingual glands, adjacent to the entoglossal cartilage (paraentoglossal glands), showed some peculiar histochemical characteristics.
