1.The large amount of PAO could be found in the cytoplasm of parenchyma in cotyledon and in the cell membranes and intercellular spaces of cortical parenchyma in phyllogen.
3.The third section is called the ileum, and it has tight intercellular junctions, allowing it to efficiently absorb fluid and begin concentrating the intestinal contents.
4.Notethat exosomes, which have lipid bilayer membranes measuringbetween 30 and 150 nm in diameter, have been illuminated to playa vital part in intercellular communication under diverse physiological and pathophysiological circumstances.
