Osteomorphs are found in the blood and bone marrow, and fuse together to form osteoclasts, the cells that are specialized in resorbing bone. Osteomorph upregulated genes are implicated in rare and common bone diseases in humans. Osteoclasts are large multinucleated bone-resorbing cells formed by the fusion of monocyte/macrophage-derived precursors that …
