Distinct effects of two CD44 isoforms on tumor growth in vivo.

Abstract excerpt

Tumor growth is dependent in part on interactions between tumor cells and the extracellular matrix of host tissues. Expression of the cell surface glycoprotein CD44/Pgp-1, which mediates cell-substrate interactions is increased in many types of malignancies, but the role of CD44 in tumor growth is largely undefined. Recently, two isoforms of CD44 have been identified: an 80-90 kD form, which has high affinity for...
