Alterations in Epithelial Polarity and the Pathogenesis of Disease States
2 Jun 1994
Abstract excerpt
Polarized epithelial cells transport ions, water, and macromolecules from one biologic compartment to another. These processes include absorption by enterocytes and renal tubular cells; secretion by hepatocytes, endocrine cells, and exocrine cells; and exchange by alveolar and capillary endothelial cells1,2. The performance of these functions depends on a surface membrane organized into structurally,...
