An ultrastructural, cytochemical, autoradiographic and radioisotopic uptake study has been made of the sulcular epithelium in an attempt to explain the function of the prominent Golgi apparatus and the associated membrane bound granules which are found in the cytoplasm of the sulcular epithelial cells. Some of the granules appear to be lysosomal in nature in that they are acid phosphatase positive and in some instances they appear to release their hydrolytic enzymes into the intercellular space. The evidence presented suggests that many of the remainder of the granules are related to the production of materials which become incorporated into the extraneous cell surface coat of the epithelial cells. The radioisotope experiments suggest that the rate of synthesis of cell coat material is higher in the sulcular epithelium than it is in the oral epithelium
