The extracellular matrix-myosin pathway in mechanotransduction: from molecule to tissue.

ABSTRACT

Mechanotransduction via the extracellular matrix (ECM)-myosin pathway is involved in determining cell morphology during development and in coupling external transient mechanical stimuli to the reorganization of the cytoskeleton. Here, we present a review on the molecular mechanisms involved in this pathway and how they influence cellular development and organization. We investigate key proteins involved in the ECM-myosin pathway and discuss how specific binding events and conformational changes under force are related to mechanical signaling. We connect these molecular mechanisms with observed morphological changes at the cellular and organism level. Finally, we propose a model encompassing the biomechanical signals along the ECM-myosin pathway and how it could be involved in cell adhesion, cell migration, and tissue architecture.
