mechanotransduction converts mechanical input into altered molecular activity or cellular behavior. A causal test separates applied mechanics from accompanying chemical changes and identifies a force-sensitive step.
Dependence of cell-state decisions on forces, deformation or the mechanical environment. Experiments must separate physical input from altered ligand presentation, survival and selection of pre-existing states.
A reciprocal relation in which molecular state changes tissue mechanics and mechanically altered conditions change molecular activity. Time-resolved perturbations distinguish feedback from correlated changes.

Mechanotransduction is the process by which cells convert mechanical stimuli from their environment into biochemical signals. This complex phenomenon allows cells to sense and respond to mechanical forces such as stretch, pressure, and shear stress. Mechanotransduction plays a critical role in various physiological processes, including: 1. **Cell growth and differentiation**: Mechanical signals can influence how cells grow, differentiate, and function. For instance, stem cells may differentiate into bone or cartilage cells in response to mechanical loading.
