Abstract

Abstract:

BACKGROUND: Mechanotransduction is an issue of concern in the study on the relationship between stress and growth. Mechano-growth factor (MGF) holds stress sensitivity, and exerts similar effect with stress in bone metabolism regulation.

OBJECTIVE: To explore the mechanotransduction during bone remodeling, and investigate the relationship between stress and growth at molecular level.

METHODS: The governing equations about the relationship between MGF and mechanical stimulation, regulation of MGF on osteoblasts and osteoclasts, regulation of MGF on RANK-RANKL-OPG signaling axis were established, and then the MGF-mediated bone reconstruction model was established to simulate the bone remodeling process under mechanical stimulation.

RESULTS AND CONCLUSION: Under the condition of disuse, there was a decrease in osteoblasts/osteoclasts ratio, bone mass and bone volume fraction, and bone resorption was more than bone formation. Under the condition of overload, there was an increase in osteoblasts/osteoclasts ratio, bone mass and bone volume fraction, and bone formation was more than bone resorption. The simulation results were in accordance with Frost mechanostat theory. These findings show that the mechanobiological model of bone remodeling based on MGF can simulate the bone remodeling process under mechanical stimuli, and achieve mechanotransduction.
