Cell adhesion: implication in tumor progression.

Changes in the adhesive properties of neoplastic cells, as well as intracellular signaling mediated by cell surface adhesion molecules, play essential roles in the development and progression of cancer. In this review, we summarize the recent progress in understanding the biology of cell adhesion molecules (CAMs) as well as their clinical significance as prognostic biomarkers or as potential therapeutic targets in a variety of malignancies.
