STI571 (Glivec) suppresses the expression of vascular endothelial growth factor in the gastrointestinal stromal tumor cell line, GIST-T1

Figure 4 Expression of VEGF determined by flow cytometry. 2×10⁶ GIST-T1 cells were treated with/without STI571 or SCF as described in “Materials and methods”. A: Control (normal rabbit IgG); B: non-treated (VEGF antibody); C: STI571 (1 μg/mL); D: SCF (10 ng/mL); E: SCF (10 ng/mL)+STI571 (1 μg/mL). MFI, mean fluorescent intensity.
