In our experiments, alternatively, we observed that disturbed shear anxiety prevents cytoskeletal reorganization by suppressing target genes, contributing in this way, for the modification of endothelial cell morphology and alignment as shown by cell microscopical photos. Due to the fact cytoskeleton can also be important in the maintenance of endothelial barrier function and integrity, the alteration within this intracellular structure may possibly for that reason contribute to modify endothelium permeability.
