Dense-cored vesicles and unusual lamellar bodies in type III gustatory cells in taste buds of rabbit foliate papillae

Some type III cells in taste buds of rabbit foliate papillae have greatly increased numbers of dense-cored vesicles. Such cells also contain unusual lamellar bodies that resemble those in alveolar type II cells; they consist of alternating dense and light layers with a periodicity of about 4.4 nm. The precise relationship between the vesicles and the lamellar bodies is unknown.
