Silver methods applied to semithin sections to identify peptide‐producing endocrine cells

Abstract
Silver methods were successfully applied to semithin sections of Epon‐embedded material, in bronchial epithelium of the chicken lung, as well as in stomach and gut of the frog. Silver methods with some modifications characterize very well the cytoplasmic argyrophilic and argentaffin granules. They give good results in plastic‐embedded material.
