Coined/History 
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.
