Fig. 2From: Characterization and anti-uterine tumor effect of extract from Prunella vulgaris L.Apoptosis and cell cycle of PVE and GLC by cell flow cytometry analysis. The HUMC Cells were treated with varying PVE concentrations of 0, 0.25, 0.5, 0.75, and 1.0 × IC50 (2.6 mg/ml) or GLC concentrations of 4.65 mg/ml. After 24 h treatment, the cells were analyzed by Annexin V and PI staining. Percentages of cells in both early and late apoptosis were counted (a: apoptosis; b: apoptosis rate, compared with the blank group, #p < 0.05, compared with the GLC group, *p < 0.05; c: cell cycle)Back to article page
