Invasive growth is one of the hallmarks of cancer malignancy. To date, a significant body of evidence is accumulating in favor of the notion that invasive growth results from the cross-talk between cancer cells and the host stromal cells, comprising fibroblasts (myofibroblasts), endothelial cells, and leukocytes, all of which are themselves invasive. In this review we describe cross-talk between invasive cancer cells and host stromal fibroblasts and an impact of pericellular microenvironment on the invasive phenotype of cancer cells, focusing on two molecules, extracellular matrix metalloproteinase inducer (EMMPRIN, also known as tumor cell-derived collagenase stimulatoty factor, basigin, CD147) and hepatocyte growth factor (HGF, also known as scatter factor). Both molecules are deeply involved in the regulation of invasion-associated cellular activities, such as pencellular proteolysis, migration and ectopic sunrival of cancer cells.
