Electron microscopy analysis of endothelial cell-cell borders
Confluent human umbilical vein endothelial cells (HUVECs) either (B) unstimulated or (A) tumour necrosis factor-α-stimulated for 18 h were fixed and processed for electron microscopy. Arrows denote actin filament bundles, whilst arrowheads indicate position of electron-dense junctional structures. Inset: cartoon of panel A illustrating placement of stress fibres with respect to junctional contacts, confirming a connection between junctions and actin filaments, which is not observed at linear junctions (B).
