Digitally colored TEM images of the liver in molly fish. A The bile ductule lined with epithelial biliary cells (dark blue) that were connected to each other by desmosomes and tight junction (arrowheads). The biliary cells showed cytoplasmic vacuoles (Cv) and lysosomes (Ly). B The apical surface of the biliary cells showed numerous microvilli (arrowheads), which were projected into the bile ductules. C Bile duct (dark blue) lined by high cuboidal cells with prominent microvilli projected into the duct lumen (square boxed areas). Bile canaliculi (green) located between hepatocytes showed numerous microvilli (rectangle boxed areas)
