Abstract

One of the critical events in tumor growth and metastasis is the interaction between tumor cells and host tissue stroma, mediated by different adhesion receptor repertoires in different tumor cell types. Several lines of evidence indicate that interaction between the hyaluronan receptor CD44, expressed on tumor cells, and host tissue stromal hyaluronan can enhance growth and invasiveness of certain tumors. Disruption of CD44-hyaluronan interaction by soluble recombinant CD44 has been shown to inhibit tumor formation by lymphoma and melanoma cells transfected with CD44. Since hyaluronan is a ubiquitous glycosaminoglycan polymer from which oligosaccharides of defined size can be readily purified, we tested the ability of hyaluronan oligomers to inhibit tumor formation by subcutaneously (s.c.) injected B16F10 melanoma cells. Our results indicate that hyaluronan oligomers injected at concentrations as low as 1 mg/ml can markedly inhibit B16F10 melanoma growth, providing a potentially attractive reagent for the control of local tumor development.
