Description
Book SynopsisAn emerging field at the interface of biology and engineering, mechanobiology explores the mechanisms by which cells sense and respond to mechanical signalsand holds great promise in one day unravelling the mysteries of cellular and extracellular matrix mechanics to cure a broad range of diseases. Mechanobiology: Exploitation for Medical Benefit presents a comprehensive overview of principles of mechanobiology, highlighting the extent to which biological tissues are exposed to the mechanical environment, demonstrating the importance of the mechanical environment in living systems, and critically reviewing the latest experimental procedures in this emerging field.
Featuring contributions from several top experts in the field, chapters begin with an introduction to fundamental mechanobiological principles; and then proceed to explore the relationship of this extensive force in nature to tissues of musculoskeletal systems, heart and lung vasculature, the kidney glomerulus
