Histochemical Study of the Ameloblasts and the Enamel Matrix in Rat Molars

Abstract
Neutral polysaccharides which became partially converted into strongly acidic polysaccharides were present in the enamel matrix of the first maxillary molar of rats aged 2-16 days. These polysaccharides may serve as a framework on which the Ca salts are deposited. An intracellular (sudanophilic) unsaturated-lipid which probably serves as a source of reserve energy for the cell, and an intercellular lipid (a lipoportein) which may play a role in calcification were detected.
