Abstract

Recent studies demonstrate that osteocyte processes directly attach to the canalicular wall at discrete, infrequent collagen hillocks, most likely via integrins. In the current paper, we develop a model for these attachment complexes to determine whether they would induce focal strain amplification. Our model predicts that axial strains on the osteocyte process membrane in the vicinity of integrin-based attachments are approximately two orders of magnitude larger than whole bone tissue strains due to the sliding of actin filaments relative to integrin-based attachments. This large strain amplification can provide a mechanism for osteocyte excitation.
