GO-triggered cell death of erythroid cells through apoptosis. (A) Representative FACS images describing fetal liver cell death upon GO treatment at 20 μg/ml for 24 h using Annexin V and PI staining. (B) FACS analysis of relative fluorescent intensity reflecting ROS content after GO exposure at various concentrations at different time points in fetal liver cells. ANOVA was used to determine the mean difference in cells treated with GO at different concentrations and along time course compared to control.
