Exploiting biomechanics to direct the formation of nervous tissue

Abstract Forces and displacements play essential roles in the development and maintenance of all living organisms. The biomechanics in living systems include traction in cell motility, motor proteins driving cellular transport, tensegrity of the cytoskeleton and mechanotransduction of signal pathways. In the past few decades, we have learned a great deal about how biomechanics is important in the development, maintenance, and repair of the nervous system. In this review, we critically assess recent advances in utilizing mechanical stimuli towards exploiting the directed growth and formation of nervous tissue. We discuss current systems that recapitulate the mechanical environment surrounding neural tissues as engineering solutions to explore the relationship forces play in modifying neurons and their processes as well as exploit these processes to enhance regeneration and repair.
