Fig. 3. Inhibitory effect of methanolic extract from Chlorella vulgaris(A) and Parachlorella sp.(B) on growth of DLD-1, MDA-MB 231, MIA PaCa-2, and HCC 827 cancer cells. The cells were treated with extracts of Chlorella vulgaris and Parachlorella sp. for 24 hr and the cell viability was assessed by WST-1 assay. Data represent the mean ± SEM of three independent experiments. *p < 0.05, **p < 0.01, and ***p < 0.001 versus non-treated cells.
