Metalloproteinases in osteoarthritis]. Articular chondrocytes were cultured on poly( ɛ -caprolactone) materials whose surfaces were either flat or honeycomb-patterned. Mobasheri A, Kalamegam G, Musumeci G, Batt ME. Would you like email updates of new search results? 2003;35:401–404. In response to trauma or inflammation, the metabolic activity of the chondrocyte is increased in response to catabolic and anabolic factors that regulate remodeling of … Osteoblasts replace calcified cartilage with spongy bone. Imbalance in their function leads to degenerative diseases like Osteoarthritis (OA). - Definition, Causes, Symptoms & Treatment, What Is Tendonitis?
