Carbohydrates on epithelial cell surfaces of oral mucosa and skin from various anatomical regions of C3H mice were demonstrated with fluoresceinated lectins. With an individual lectin, all tissues showed a similar pattern of binding: most lectins showed binding to the cell surfaces of all nucleated cell layers although that to basal cells was often weaker and was occasionally absent. The corneocytes did not typically bind lectins except that the follicular keratin of the tail showed a uniform and intense fluorescence with several lectins. Basement membrane bound all lectins. The results indicate that detectable changes occur in the cell-surface carbohydrate composition as cells differentiate but that cell-surface carbohydrates do not differ markedly from one region to the next. Lectin binding may provide a convenient method of detecting functional changes in normal cells and in cells which have undergone experimental or pathological changes.
