Objectives: The aim of this study was to determine the changes in the morphology and cytoskeleton organisation of endothelial cells (EC) determined by exposure to a laminar flow. Cultured EC were exposed to a wall shear stress of 6 dyne/cm2 for 24 hours. Chief outcome measures: The morphology of EC was analysed by light and scanning electron microscopy. The organisation of the cytoskeleton was determined by double fluorescence labeling with antibody anti-vimentin, anti-vinculin, anti-tubulin, and with rhodamine-labeled phalloidin. Results: EC exposed to laminar flow become round-shaped with decreased area of adhesion to the substrate. There was a clear reorganisation of the cytoskeleton after exposure to shear stress; the distribution of actin changed from a stress fibre pattern to a more diffuse membrane-associated distribution. These changes in shape and cytoskeleton organisation were reversible after a 48-hour resting period. Conclusions: EC respond to laminar flow in a predictable manner and these findings may be correlated to the functional changes of EC observed after exposure to shear stress. © 1995 W. B.
