It has been reported that stiff tissues result in more aggressive cancer development than soft tissues, meaning that the composition of our tissues, including the extracellular matrix has a profound effect on our susceptibility to cancer. Using your understanding of lectures 29-33, what components and properties of extracellular matrix affect tissue stiffness and what properties of cell behaviour are likely to be affected by that stiffness.
