Metformin Treatment Inhibits Motility and Invasion of Glioblastoma Cancer Cells

Figure 1

Metformin treatment decreases cell viability in SF268 and U87 cells. Cells were treated with increasing concentrations of metformin (1, 1.5, 2, 2.5, 5, 10, 15, 20, or 50 mM) for 24 h or left untreated. Cell proliferation was assessed using the WST-1 reagent. The data represents the mean ± SEM from 3 independent experiments.
