The effect of hyaluronic acid on proteoglycan synthesis and secretion by chondrocytes of adult cartilage

Abstract
The chondrocyte is a specialized cell that synthesizes proteoglycans of a type found only in cartilage and nucleus pulposus. These proteoglycans are distinct in forming multiple aggregates of unique structure in which hyaluronic acid provides a central chain to which many proteoglycan molecules are bound at one end only.
