The representative immunofluorescent staining confocal images demonstrate the VE-Cadherin distributions of cultured vascular network, a statically cultured endothelial monolayer, and an intact rat mesenteric venule.

<p>A. The schematic image of the network with selected regions as shown in B-D. B-C. VE-Cadherin and cell nuclei staining were shown at the first and third branching regions. D₁-D₂. VE-Cadherin and cell nuclei staining were shown at the top and bottom surfaces of the second branching regions, respectively. E. VE-cadherin junction distribution of HUVECs cultured under static condition. F. VE-cadherin distribution of endothelial cells from an individually perfused intact rat venule.
