CD44 is a cell surface adhesion receptor that is highly expressed in many cancers and appears to regulate metastasis. Its recruitment to the cell surface and its interaction with extracellular matrix ligands promote the migration and invasion processes involved in metastases. Therefore, elevated levels of soluble CD44 in the serum of cancer patients can be used as a marker for the existence of tumor cells. The over-expression of this receptor is particularly seen in breast cancer cells. This discovery may allow for specific cancer cells to be detected rather than invading healthy cells through chemotherapy to get rid of defective muted ones.
