Fine structure and intercellular junctions of a freshwater teleost (Pimelodus maculatus) hepatocytes by freeze-fracture replicas.
The Pt-C replicas of a freshwater teleost hepatic cells were studied by electron microscopy. The surface of hepatocytes bordering the perisinusoidal space is studied with numerous microvilli. Cell-to-cell attachments are made through gap junctions and spot desmosomes. Tight junctions are found between hepatocytes close to the bile canaliculi. Some of the numerous corpuscular elements found in the cytoplasm can be identified as organelles, specially if their interiors are partially exposed by cleaving.
