Osteoclast An osteoclast (from the Greek words for bone (ὀστέον), and broken (κλαστός)) is a type of bone cell that breaks down bone tissue. This function is critical in the maintenance, repair, and remodelling of bones of the vertebral skeleton.The osteoclast disassembles and digests the composite of hydrated protein and mineral at a molecular level by secreting acid and a collagenase, a process known as bone resorption.his function is critical in the maintenance, repair, and remodelling of bones of the vertebral skeleton.
