Function of an osteoclast
WebBone homeostasis is maintained by a balance between bone resorption by osteoclasts and bone formation by osteoblasts. Osteoblasts not only play a central role in bone formation by synthesizing multiple bone matrix proteins, but regulate osteoclast maturation by soluble factors and cognate interactio … WebOsteoblasts have three main functions: Growing new bones (bone formation). Reshaping bones to help them change as you age (remodeling). Healing damaged or broken bones. Osteoblasts are triggered by chemical reactions or hormones when a bone grows or changes. They create and release (secrete) a mix of proteins called bone matrix.

Once activated, osteoclasts move to areas of microfracture in the bone by chemotaxis. Osteoclasts lie in small cavities called Howship's lacunae, formed from the digestion of the underlying bone. The sealing zone is the attachment of the osteoclast's plasma membrane to the underlying bone. Sealing zones are bounded by belts of specialized adhesion structures called podosomes. Attachment to the bone matrix is facilitated by integrin receptors, such as αvβ3, vi… WebFigure 4. Osteoclasts and antigen presentation.
