CD44 and cancer: Since MTS and CD24- and CD44-overexpressing cancer stem-like PANC1 cells show high expression of fucosylated glycans using specific lectins binding to the spheroid cells [32], we examined prior to spheroid formation the cell surface sialylation of monolayer MCF-7, MCF-7 TMX cells (Figure 3), and PANC1 and PANC1-GemR cells (Figure 4).
