Semithin sections of the stromal and cellular constituents of molly fish liver stained with toluidine blue. A and B The biliary tract system showed isolated type of distribution, the bile ductules (asterisks) were found independently within the hepatic parenchyma and were enclosed by connective tissue sheath (arrowheads). Hepatocytes (Hc) showed vacuolated cytoplasm containing abundant glycogen and lipid droplets. C and D The biliary tract system showed the biliary venous tract (BVT) type of distribution, the bile ductules (asterisks) were supplemented with portal venules (V) and were recognized within the hepatic parenchyma. Hepatocytes (Hc) showed deeply stained cytoplasm containing deeply stained inclusions. Telocytes (black arrowheads) and some immune cells (white arrowheads) were recorded within the connective tissue sheath surrounding the bile ductule. E Kupffer cells (arrowheads) showed cytoplasmic processes that protruded into hepatic sinusoid (asterisks). F Melanomacrophage center (arrowhead) was in close topographic association to bile ductule (BD).
