[The role of cations and surface membrane proteins in the adhesion of rat liver parenchymal cells. II. The influence of calcium ions on the structure of cell contacts].
The structural interrelations of hepatocytes, under the rat liver perfusion with calciumless solutions, were studied with the electron microscopy. Lantanum chloride, alcian blue and ruthenium red were used for revealing the intercellular space, specialized junctions and cell coats. Significant alterations in the interelations of the hepatocytes after a long liver perfusion (1.5h) were discovered. The structure of the specialized cell junctions and the space intercellular width under a 15-20 min. liver perfusion remained unchanged. The results obtained suggest the important role of Ca2+-ions and supramembranic material in the cellular adhesion.
