Some Observations Have Suggested to Researchers That Substances Associated with the Extracellular

Some observations have suggested to researchers that substances associated with the extracellular matrix may be involved in cell migration. This has been observed with the cell marker CD44 on the surface of cancer cells and their ability to be separate from one another and to easily metastasize to other regions of the body. This is most likely due to the interaction of CD44 and

A) elastin.
B) chondrotin sulfate.
C) hyaluronate.
D) fibronectins.
E) ICAMs.
