Figure 4: The antiproliferative activity of dichloromethane/methanolic extract of Chlorella pyrenoidosa on HeLa cells. Cells were incubated with different concentrations of the plant extracts (ranged from 6.25 to 800 ìg/ml) for 48 h. Cell viability was determined by the MTT assay (n = 4). Viability curves: Percentage viability = absorbance of test wells/ absorbance of control wells) × 100) plotted against the concentration of extract
