Types of lymphatic cells

    • Molecular characterization of lymphatic endothelial cells

      Lymphatic capillaries are responsible for the uptake of the components from the interstitium. Although endothelial cells (EC) of lymphatic capillaries have many properties in common with the endothelium of blood vessels, they also have distinct structural characteristics reflecting their specific functions (4–7). Lymphatic

      As seen in lymphatic tissues, these cells are 4 to 8 µm in diameter and contain a deeply stained nucleus surrounded by a thin rim of cytoplasm that may be expanded slightly at one side of the cell. Although rounded in shape in the blood or lymph, in tissues the cells are crowded together and assume various polyhedral shapes due to compression. The

This lymphatic invasion was likely to start at the hilar region and spread out in fat tissue (Fig. 6).
