Fig. 2. Annexin V-FITC staining assay for analysis of the apoptotic cell death in human endometriotic cells. 12Z cells were treated with luteolin (15, 30, and 60 μM) for 48 h and then stained with Annexin V-FITC. The translocation of phosphatidylserine was detected by flow cytometry. The graph indicates the percentages of apoptosis. *p<0.05 as compared with the control group.
