Anti-proliferative and pro-apoptotic effects of tectorigenin on hepatic stellate cells

Figure 4 Flow cytometry-evidenced apoptosis of hepatic stellate cells-T6 cells upon exposure to tectorigenin. Cells were incubated for 24 and 48 h with tectorigenin at 20, 40, 60 and 100 μg/mL, respectively, followed by being stained with fluorescein isothiocyanate-conjugated annexin V and propidium iodide. Bars represent mean ± SD (^aP < 0.05, ^bP < 0.01).
