Figure 5. The effect of the TGF-β1 treatment on the expression of immune modulatory cell surface molecules.
Bar graphs show flow cytometry data of at least 3 independent stimulation experiments (n ≥ 3) normalized to the untreated control. (A) HLA-ABC, B7-H2, and B7-H3 are upregulated, whereas HLA-BC and ICAM-1 are down-regulated after TGF-β1 treatment in MZ2733RC. (B) In MZ2858RC, all tested proteins are down-regulated after TGF-β1 treatment. (n.s.: not significant, *p ≤ 0.05, n.d.: not detected).
