In contrast, an anti-CD44 mAb (5-mG2a-f) did not inhibit the growth of SAS or HSC-2 compared to control mouse IgG2a (Fig. S2B), indicating that 5-mG2a-f did not affect the cell growth of oral cancer cell lines in anchorage-independent condition. Here, CD44 is linked to lip and oral cavity carcinoma.
