Cellular Adaptation to Mechanical Stress Emerges via Cell Shrinkage Triggered by Nonlinear Calcium Elevation

Advanced Science, EarlyView.
Here, a decision‐making mechanism underlying mechanical adaptation is demonstrated. This study demonstrates that cellular adaptation to mechanical stress can be induced by applying low‐amplitude stretch to cells. When the stretch reaches a critical amplitude threshold, it triggers Ca2⁺‐dependent positive feedback, which induces cholesterol efflux and ...
