How does osteoclasts work
WebThe osteoclast is a multinucleated highly specialized cell specifically equipped for the resorption of a mineralized matrix (Fig. 3.21 ). Osteoclasts are derived from the hematopoietic stem cell. This cell gives rise to erythrocytes, granulocytes, mast cells, megakaryocytes, lymphocytes, and macrophages.
