Recent Advances in Mechanobiology of Osteosarcoma

Mechanotransduction is a key process by which cells perceive extracellular mechanical cues/intercellular physical interactions and transform them into intracellular biochemical signals. This physiological process is crucial during bone development and bone remodeling throughout childhood and adult life, whereas several aberrations during this process have emerged as a distinct pathogenic molecular entity in bone maladies and tumor formation. The present review focuses on recent advances regarding the mechanobiology of osteosarcoma, the most common type of bone cancer. Special emphasis is given on the mechano-responsive signal transduction pathways underlying osteosarcoma pathology and on specific mechanosensitive molecules engaged in osteosarcoma development. J.
