Mechanobiology

Mechanobiology is an interdisciplinary field that explores the reciprocal relationship between mechanical forces and biological processes in living organisms. It investigates how mechanical cues, such as forces, stiffness, and topography, influence cellular behaviour, tissue development, and disease progression. This field integrates principles from biology, physics, engineering, and materials science to unravel the mechanistic basis of mechanotransduction—the process by which cells sense and respond to mechanical stimuli. At the cellular level, mechanobiology studies how mechanical forces affect various cellular processes, including cell adhesion, migration, proliferation, differentiation, and gene expression. Cells are equipped with mechanosensitive structures, such as integrins, focal adhesions, and cytoskeletal components, which enable them to detect and respond to mechanical cues from the extracellular environment. Mechanobiology also investigates the role of mechanical forces in tissue development and homeostasis. During embryonic development, mechanical forces generated by cell-cell interactions, cell-matrix interactions, and tissue morphogenesis drive tissue patterning, organogenesis, and morphogenesis. In adult tissues, mechanical cues regulate tissue remodelling, wound healing, and regeneration processes, maintaining tissue integrity and function.
