title: Membrane transport properties of bovine articular cartilage.
abstract: The thermodynamic parameters which define transport of nonelectrolytes through bovine articular cartilage membranes were evaluated. H3HO, glucose and sucrose were used as permeants. These solutes permeate more readily through the upper layers (near the articular surface) than through the denser deeper layers approaching bone. Cartilage is similar in many respects to a swollen cellulose gel. Viscous-flow contributes importantly to transport within cartilage thus greatly enhancing the movement of nutrients.
