Network of proteins influences the advancement of osteoarthritis

A network of carbohydrate binding proteins—so-called galectins—plays an important role in the degeneration of cartilage in osteoarthritis. A research group at the MedUni Vienna was able to demonstrate this correlation, ...

Defense against joint degeneration

During cartilage development, chondrocytes secrete the extracellular matrix (ECM) and embed within the same environment. During progressive joint disease, such as osteoarthritis (OA), dysregulation of the process can lead ...

Cartilage

Cartilage is a type of dense connective tissue existing within many joints. It is composed of specialized cells called chondrocytes that produce a large amount of extracellular matrix composed of collagen fibers, abundant ground substance rich in proteoglycan, and elastin fibers. Cartilage is classified in three types, elastic cartilage, hyaline cartilage and fibrocartilage, which differ in the relative amounts of these three main components.

Cartilage is found in many areas in the body, including the articular surface of the bones, the rib cage, the ear, the nose, the bronchial tubes and the intervertebral discs. Its mechanical properties are intermediate between bone and dense connective tissue like tendon.

Unlike other connective tissues, cartilage does not contain blood vessels. The chondrocytes are fed by diffusion, helped by the pumping action generated by compression of the articular cartilage or flexion of the elastic cartilage. Thus, compared to other connective tissues, cartilage grows and repairs more slowly.
