EM 182 Lymphatic Vessel

Lymphatic Capillary

Transmission electron micrograph (TEM) of a lymphatic capillary. The flattened endothelial cells are attached to each another by adherent junctions. The basement membrane is poorly developed.

  • Nucleus (blue) / Nucleolus (yellow) / Nuclear Envelope (purple)
  • Golgi Apparatus (yellow)
  • Mitochondria (red)
  • Endoplasmic Reticulum (cyan)
  • Cytoplasm (green)

Anchoring filaments run from the outer surface of the endothelium into the surrounding bundles of collagen fibers (brown). They pull on the lymphatic vessel wall to keep the vessel open.

Unlike blood vessels, lymphatic capillaries do not perivascular cells associated with them.
