the authors show how physical forces drive mechanosensing by applying dynamic force regimes to cells through different techniques including Optical Tweezers.
To measure the forces applied on cells with Optical Tweezers, they use the SENSOCELL force sensor module: Lunam T-40i. This module integrates our unique force spectroscopy technology allowing direct access to the forces applied by the optical tweezers on any trapped object without requiring any tedious and prone-to-error calibration process.
The authors found different responses depending on the forces applied and show how these similar behaviors are seen at the organ level.
This work provides a unifying mechanism to understand how cells respond not only to directly applied forces, but also to passive mechanical stimuli such as tissue rigidity or ECM ligand Distribution.
