Figure 1. Figure 1.

The lumen of rat mesenteric vessel with valve. Series of computer‐processed 3D images (Leica Confocal Software v.2.60) positioned at different angles of view to illustrate the geometry of the lymphatic valve. The 3D projection was generated from a series of images taken, using confocal microscope after loading of live rat mesenteric lymphatic vessel with an intravital fluorescent dye. Transmural pressure is ∼7cm H2O. flow gradient across valve is 0cm H2O and vessel diameter is ∼120 um (unpublished observations).
