Function of an osteoclast
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. WebA. Osteoclastogenesis. Osteoclast differentiation and function is under the control of neighboring immature osteoblasts or bone lining cells of the endosteum or periosteum …

Did you know?
WebOsteoclasts are primarily responsible for the catabolic action of PTH on bone by increasing resorption. PTH stimulates increased numbers and activity of osteoclasts; however, osteoclasts do not have receptors for PTH. Receptors for PTH are present on osteoblasts. Isolated osteoclasts respond to PTH only with the concurrent presence of osteoblasts. WebNational Center for Biotechnology Information
