The Life of Osteoclasts
Year March, 2002
Time 20 min.
Summary Bone is continually remodeled by osteoblasts which deposit fresh layers of bone and osteoclasts which erode bone matrix. Previous studies demonstrated that osteoclasts are differentiated from monocytes/macrophages in bone marrow.

The aims of this film are to record the site where osteoclasts are born and how they grow and acquire functions. We could film in microscopic image that cells collected from bone marrow matured and differentiated to osteoclasts.

Furthermore, the effect of calcitonin, one of bone metabolism-related hormones, was observed under microscope controlling differentiation and function of osteoclasts. Actin and tubulin fibers were visualized by fluorescent staining, and we could observe for the first time the dynamic change of these cytoskeletons in the osteoclasts.

It can be said that this is the first video to demonstrate the life of osteoclasts with the microscope image.
