Secretory glycoconjugates in the epithelium of the goat prostate

Summary Secretory glycoconjugates in the epithelium of the goat prostate were investigated with various electron microscopical histochemical methods that involved periodic acid—thiocarbohydrazide—silver proteinate, colloidal gold-labelled lectin and related procedures. The three types of cells in the epithelium previously differentiated with the light microscope were substantiated: mucus-producing cells, protein-secreting cells and cells intermediate between both types. These three cell types contained varying amounts of neutral glycoconjugates; the histochemical nature of these carbohydrates was determined with particular emphasis upon the histophysiological functions of the accessory sex glands.
