Figure 7

The orientation of remodeled branch angles. A) A SEM photomicrograph of a corrosion cast obtained 30 days after the onset of TNBS-induced colitis (bar=100um). Acute branch angles, likely reflecting structural remodeling, are highlighted (elipses). Note the similar length and orientation of the parallel segments within the highlighted regions; specifically, the parallel segements of vessels at the vessel bifurcation. Two other examples (N=2 mice) of nonrandom remodeling are shown in the polar graphs (B,C). The length and orientation of the parallel segments are shown for colitis (black) and control (gray) mice. D) Schematic illustration of the periodic variation in converging (closed circles) and diverging (open circles) bifurcations created by a unidirectional flow field (arrows) in the colon mucosal plexus.
