Subsurface cisternae, broad flattened sacs with varying numbers of fenestrae lying along the lateral plasma membrane, in murine hepatocytes were studied in thin sections and freeze-fracture replicas. Subsurface cisternae extended from pericanalicular to perisinusoidal areas of the cytoplasm of closely adjoining hepatocytes. Subsurface cisterna was made up of paired membranes, an inner cisternal membrane facing the cell interior and an outer cisternal membrane facing the lateral plasma membrane. The inner cisternal membrane was continuous in some locations with the endoplasmic reticulum. Subsurface cisterna was fenestra-rich at its portions underneath gap junctions. Subsurface cisternae appeared as anastomosing tubules at pericanalicular and perisinusoidal ends and joined with tubulovesicle networks seen in these cytoplasmic areas.
