Literally meaning: “what breaks bones”
Origin: Anc Greek
+κλάω,ώ/ klao, klo(=break, prune)
Osteoclasts were discovered on bone surface by Swiss anatomist Albert von Kolliker (1817-1905), in 1873. Kolliker named them “osteoklasts” because of the name of a surgical instrument used to fracture bones, and suggested a role of cells in bone resorption. The origin of osteoclasts since then have been a controversial subject.
Osteoclast is a multinucleated cell which is associated with deformation of bone. Osteoclasts and osteoblast regulate together the amount of bone mass.
