In the epithelia and endothelia, tight junctions regulate the movement of several substances through the paracellular pathway, maintaining several gradients between apical and basal compartments including osmolality and hydrostatic pressure. In this study, we show that the change of hydrostatic pressure gradient affected tight junctions as well as actin cytoskeleton, cell height and transcellular ion transport. Hydrostatic pressure gradient from basolateral to apical side increased transepithelial conductance and altered claudin-1 localization within several tens of minutes. These changes were promptly restored by the elimination of hydrostatic pressure gradient. Hydrostatic pressure gradient also induced dynamic changes in the actin structure and cell height. We further found that hydrostatic pressure gradient from basolateral to apical side stimulates transcellular Cl(-) transport. Our present findings indicate that the epithelial cell structures and functions are regulated by the hydrostatic pressure gradient which is generated and maintained by the epithelia themselves.
