Cell-Matrix Mechanics

Fall 2016

This course teaches the effects of mechanical forces (strains) on cells and how cells generate mechanical forces by their contraction. Critical to both topics is the mechanical behavior of the extracellular matrix (ECM), which the cells have synthesized and remodeled. The ECM affects cell behavior by mediating exogenous mechanical strains, which stimulate certain cellular processes.
