WebChondrocytes contain large amounts of glycogen and begin to secrete alkaline phosphatase. Zone of calcification In this zone, chondrocytes are either dying or dead, leaving cavities that will later become invaded by bone-forming cells. Chondrocytes here die when they can no longer receive nutrients or eliminate wastes via diffusion. Web5. Bone: Chondrocytes secrete substances that repel the attraction or growth of blood vessels into the cartilage tissue. With the death of the hypertrophied chondrocytes, blood vessels are not repelled but invade the calcified lacunae instead. The blood vessels bring osteoblasts that attach to the calcified walls and begin to develop ...

WebIn addition to stimulating osteoclast function, TNF-α promotes the recruitment of mesenchymal stem cells and induces apoptosis of hypertrophic chondrocytes during endochondral bone formation. Its absence delays the resorption of mineralized cartilage and, consequently, prevents the formation of new bone. WebAs the matrix surrounds and isolates chondroblasts, they are called chondrocytes. Unlike most connective tissues, cartilage is avascular, meaning that it has no blood vessels supplying nutrients and removing metabolic wastes. All of these functions are carried on by diffusion through the matrix.
