Popis: Similar catabolic features were found in macrophages of melano-macrophage centers of sturgeon liver and Kupffer cells of hibernating frogs and tadpoles underdoing metamorphosis. Catabolic process includes 4 stages: 1) intact phagocyted erythrocytes; 2) phagosomes with erythrocyte-like matrix density containing dense ferritin granules distributed between hypertrophied Golgi complex and smooth endoplasmic reticulum; 3) phagosomes with membrane structures and electron dense granules; 4) phagosomes with melanin granules. Products of erythrocyte catabolism are released through the bile duct. The origin of melanin granules is discussed.
