Effect of As2O3 on the viability and proliferation of HUVECs.
Rapidly proliferating, 70% to 80% confluent HUVECs were incubated in culture medium with different concentrations of As2O3 for the time period indicated. The number of viable cells was counted in triplicate by means of the trypan blue exclusion assay. The results show the mean ± SD of 3 independent experiments.
