Abstract

Normal and autotransplanted salamander pituitary glands were studied by light and electron microscopy. Frozen sections of glutaraldehyde-fixed material were incubated for demonstration of acid phosphatase, a "marker" enzyme for lysosomes. Acid phosphatase is demonstrable in the agranular membrane systems and vesicles associated with the Golgi apparatus, in newly formed secretory granules, and in lysosomes of both the normal and autotransplanted par distalis. Among the lysosomes, autophagic vacuoles containing secretory granules are more common in the hypersecretory cell types of the autotransplanted pituitary than in the normal gland.
