Abstract

In the study for the article cited above, the authors used cell line ECV304 as human umbilical vein endothelial cells to investigate their proliferation after treatment with tetrandrine. However, this cell line has been demonstrated to be cross-contaminated by T24 human bladder carcinoma cells (Dirks et al. In Vitro Cell Dev Biol Anim 1999; 35:558-9). The authors were not aware of the cross-contamination of the ECV304 cell line and acknowledge that the respective data are not valid as effects of tetrandrine on endothelial cells.
