| Research Abstract |
This report describes that a dynamic model of mechanical sensing system of an osteoblast is constructed by considering a cell as an intelligent structural system with sensors, controllers, and actuators, and that the effective frequency and amplitude of mechanical vibration on bone formation is identified. As a result, we have developed an experimental method to obtain the relationship between mechanical deformation and biochemical response of a cell and have shown that the mechanical sensing system of a cell can be modeled. Furthermore, we have shown that the cell proliferation is promoted with decreasing the vibration frequency and that 50 Hz is the effective frequency of bone formation.
