概要:
application/pdf<br />Departmental Bulletin Paper<br />Labyrinthine tubulovesicle networks, residents in the intercellular space between the lateral plasma membranes of adjoining hepatocytes of mice, rats, golden hamsters, guinea pigs,

and rabbits, were studied by the freeze-fracture technique. The network was seen extending from the region beneath tight-junctional meshwork to the region near the perisinusoidal space. Fractured faces of tubulovesicles appeared to be composed of concave, convex, and/or concentric particle-free membranes. Membranous blisters were also seen in the intercellular space and often joined with the network. In thin sections, myelin figures, identical structures to the network, were seen in the intercellular space between hepatocytes. Tubulovesicle network may be bile acid components which are transported through the intercellular space.

概要:
application/pdf<br />Departmental Bulletin Paper<br />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.
