Transendothelial transport of lipids in the absorbing lymphatic vessel

Intraendothelial channels have been shown in the lacteal vessels under normal conditions and during experimentally induced stasis, using ultrastructural and tridimensional reconstruction methods. Through the channels of the lymphatic endothelial wall, free lipid drainage from the interstitium into lymph was detected, although the intercellular junctions did not appear to be modified.
