Mechanotransduction - is a
cellular mechanism by which cells sense and respond to mechanical stimuli and convert them into biochemical signals that elicit specific cellular responses. Integrins (transmembrane receptor proteins) respond to signals and change the cytoskelton by triggering downstream processes that up-regulate and/or down-regulate intracellular activity as transcription factor activation and gene regulation affecting processes such as migration, proliferation, differentiation, and apoptosis. For instance, stem cells have been shown to differentiate into different cell types depending on the stiffness of the matrix on which they are grown. |
