Abstract:
Osteoclast,a huge coenocytes,originates from mononuclear macrophages or monocytic series hematopoietic precursor cell,plays an important role in the progree of bone resorption. Formation and abnormal activity of osteoclast may cause osteoprosis,rheumatoid arthritis and aseptic loosening after arthroplasty. Therefore,osteoclast is the target for treating these disease. At present,a lot of study on formation of osteoclast were reported,but the study on how to identify and degrada-tion of bone tissue is not yet reported. Bone mineral are seen as important component of identifing osteoclast ,and the research suggested that bone matrix is not the essential ingredients of activiting osteoclast ,petri dish covered by vitronectin also can make osteoclast occure certain form of bone resorption ,vitronectin plays an significant role in activiting osteoclast. Otherwise , the research found that swallowing and secretion of bone matrix degradation products is benefit for differentiation of osteoclast and maintain of function,and this may be therapeutic target for treatment of musculoskeletal disorders.
