摘要

THE METASTATIC SPREAD OF CELLS from solid tumors to distant sites, leading to the consequent development of secondary lesions, has been estimated to be the primary contributory factor in as many as 90% of cancer patient deaths. As a result, there has been considerable interest in understanding the processes that promote cancer cell dissemination to improve diagnosis and evaluate risk, as well as to identify potential drug targets that could be inhibited with therapeutic agents to reduce cancer spread (3). The ability of tumor cells, either as single cells or in collective groups, to break away from the primary mass and invade surrounding tissue is a critical element of cancer metastasis leading to lethal disease. There has been a great deal of research focused on cancer cell migration in two-dimensional (2D) and three-dimensional (3D) experimental contexts that has revealed the complex coordination between biophysical and biochemical features of migratory cells and the extracellular matrix (ECM) (6). In particular, the role played by proteases, such as matrix metalloproteases (MMP), in ECM remodeling to enable tumor cell migration has been well characterized. However, one relatively unstudied aspect is how cells migrate through ECM microtracks.
