Color 17 min. (1982) Sponsored by Teijin Pharmaceuticals Co., Ltd. And Fujisawa Pharmaceutical Co., Ltd. (Astellas Pharma Inc.) Produced by Yone Production Inc. The entire human body is made of cells, and health is maintained through the continuous process of old cells making way for new cells. Bones are no exception. This film looks into how bones are made up of cells, how they are broken up and how they are reformed. What do the cells that are continuously engaged in bone formation and bone resorption do, and how is balance maintained within the body? We look forward to future research that will explain communication between cells and workings of the various hormones that regulate bone metabolism.

Over a long process of evolution, animals developed the complex functions of bones. Not only do bones support the body, they also serve to store and release minerals that the body needs, such as calcium and phosphorus. In addition, bones are constantly being broken down and reformed, and this is controlled by vitamin D and other hormones. Vitamin D works on the cells that create bone to promote bone formation. The bones that these cells build support life itself.

Color 13 min. (1993) Sponsored by Eisai Co.,Ltd. Produced by Yone Production Inc. Bones mainly consist of three cell types; osteoclasts that break down bone tissue and osteoblasts that create bone tissue. Once bone has been created, osteoblasts are thought to play an important role in bone maintenance by remaining in bone and establishing neural connections. This film was produced with a firm focus on these osteocytes (bone cells). Yonesaku KOBAYASHI commented that the theme of this film was “wetness”. An appropriate observation in light of the fact that osteocytes exist within body fluids and perform a variety of roles using body fluids as a medium.In addition, a cut from this film was used in the introductory part of “Peking Man”. The HD digitalization of this film was made possible through financial support provided by Eisai Co., Ltd. Gratefully received. Thank you.
