Effects of the AM18W-13a extract on the proliferation of RAW264 cells. The RAW264 cells were treated with the AM18W-13a extract at concentrations of 1/10000, 1/5000, 1/1000, 1/500, and 1/100 for 24 h. The cells in the control group were left untreated. Cell proliferation was measured by the MTT assay after treatment. The values represent the mean ± SD of results obtained from experiments performed in triplicate and are expressed as percentages relative to the results obtained from the control group. The mean value of the experimental result that significantly differed from that of the control group is indicated by asterisks (∗∗p < 0.01).
