During fluid absorption induced by amphotericin B, the lateral intercellular spaces (LIS) of the dog tracheal epithelium were widely dilated as compared to untreated time controls. When fluid absorption was inhibited by ouabain, or by replacement of luminal Na by choline, amphotericin B failed to cause dilation of the LIS. These data suggest that, as in other epithelia, a significant amount of transepithelial fluid flow passes down the LIS, and that these spaces may provide the local osmotic compartment which is responsible for linking transepithelial fluid movement to active ion transport.
