Elimination of cancer cells by LPS-activated THP-1 macrophages extends to other cell lines in co-culture. Side scatter plots showing apoptosis rate (PE-Annexin V) of cancer cells a THP-1 and b NB4, after co-culturing with activated THP-1 macrophages at 0, 5, 20, and 100 ng/mL of LPS respectively. All plots showed apoptosis at 0, 5, 20, and 100 ng/mL of LPS. c A graph showing the percentage (%) of apoptosis of THP-1 and NB4 after co-culturing with THP-1 macrophages. Values in the graph are shown as means ± SEM of three trials of duplicate samples. The statistical significance was determined by one-way ANOVA (OriginPro 2019) ** P < 0.01, ns: non-significant, P > 0.05. Side scatter plots shown here is one representative out of three trials
