Hyaluronic acid may be important in permitting tumor cells to migrate through the EGM. Tumor cells can induce fibroblasts to synthesize greatly increased amounts of this GAG, thereby perhaps facifitating their own spread. Some mmor cells have less heparan sulfate at their surfaces, and this may play a role in the lack of adhesiveness that these cells display.
