Effects of TF expression on galectin-3-mediated cell aggregation. A: O-Glycanase treatment of HCA1.7+ cells reduces TF-expression on MUC1. B: Reduction of TF-expression by O-glycanase treatment abolishes the effect of galectin-3 (1 μg/ml) on HCA1.7+ cell aggregation. Data are expressed as mean ± SEM of triplicate determinations from two independent experiments. *p < 0.05.
