Major challenges OSCC management include development resistance therapy early formation distant metastases. Cancer cells (CSCs) have emerged as important players in both pathologic mechanisms. Increased fucosylation activity increased expression fucosylated polysaccharides, such Sialyl Lewis X (SLe x ), are associated invasion metastasis. However, the role CSCs has not been elucidated yet. We used spheroid culture technique obtain a CSC-enriched population compared orospheres adherent cells. found that expressed markers metastasis at higher levels, were more invasive tumorigenic, resistant cisplatin/radiation than counterparts. fucosyltransferases FUT3 FUT6 highly up-regulated, SLe adhesion by shear flow assays orospheres. Inhibition negatively affected CSCs. results confirm enriched paramount importance CSC invasion. In addition, may play key Thus, inhibition be block metastatic spread.
