The role of chondrocyte senescence in osteoarthritis

Abstract excerpt

Replicative senescence occurs when normal somatic cells stop dividing. Senescent cells remain viable, but show alterations in phenotype, e.g. altered expression of matrix metalloproteinases (MMPs); these enzymes are known to be involved in cartilage destruction. It is assumed that cells deplete their replicative potential during aging, and age is a major risk factor for osteoarthritis (OA). Therefore, we...
