Effect of spermidine on the cell viability of RAW 264.7 macrophages. The cells were treated with various concentrations of spermidine for 24 h (A) or pretreated with the indicated concentrations of spermidine for 1 h prior to LPS (500 ng/mL) treatment for 24 h (B). The cell viability was assessed by the MTT reduction assay, and the results are expressed as the percentage of surviving cells over the control cells (no addition of spermidine and LPS). Values represent the means ± SD of three independent experiments (*p<0.05 vs. the control group).
