Schematic representation of osteoclast differentiation. Macrophage Colony Stimulating Factor (M-CSF) induces hematopoietic stem cells to become osteoclast precursors, which, under influence of Receptor-Activated Nuclear κB ligand (RANKL) develop into mononucleated osteoclasts. Further, mononucleated osteoclasts undergo fusion, mediated by DC-STAMP protein, into giant multinucleated osteoclasts, which then, upon interaction with osteoblasts, differentiate into mature bone-resorbing osteoclasts with ruffled border, which secrete acids and matrix metalloproteinases.
