A Stiff Blow from the Stroma: Collagen Crosslinking Drives Tumor Progression

Matrix stiffness is an important microenvironmental cue that regulates cell growth, motility, and differentiation. In a recent Cell report, Weaver and colleagues implicate lysyl-oxidase-mediated collagen crosslinking as a contributor to tumor matrix stiffening, which leads to enhanced integrin signaling and invasive behavior in tumors
