Access through your institution Buy or subscribe Tubule epithelial cells (TECs) regulate the reabsorption of water and electrolytes; however, the role of mechanical force in driving fluid


transport by TECs is unclear. Using a microfluidic platform to mimic fluid transport, Choudhury and colleagues now show that TECs act as mechanobiological fluid pumps, actively generating


hydraulic pressure gradients across the epithelium. The trans-epithelial fluidic flux, which occurs in an apical-to-basal direction in normal TECs, declines with increasing hydraulic


pressure until a stall pressure is reached. Moreover, the researchers show that TECs change their gene expression profiles and spatial arrangements of ion exchangers in response to changes


in pressure. This is a preview of subscription content, access via your institution ACCESS OPTIONS Access through your institution Access Nature and 54 other Nature Portfolio journals Get
