Cancer metastasis and elasticity of microenvironment
… by growing them on a substrate with appropriate mechanical stiffness (Chapter 2). This metastasis-like transition is observed as a change from a flattened, epithelial cell (E cell) to a rounded, dissociated cell morphology (R cell). We have carried out a comprehensive biophysical, biochemical and …
