Osteoclasts are responsible for breaking down bone matrix through a process called resorption. They release enzymes and acids that break down the mineral and organic components of bone, allowing for the removal of old or damaged bone tissue. Fibroblasts are connective tissue cells that produce collagen and other extracellular matrix proteins, but they do not have a role in bone resorption. Osteocytes are mature bone cells that maintain bone tissue, but they do not actively break down bone matrix. Chondroclasts and chondroblasts are involved in the growth and maintenance of cartilage, not bone tissue.
