We showed that the interaction of SS RBC at 2% concentration in the presence of multimers of von Willebrand factor ( vWf ), derived from endothelial cell-derived conditioned medium ( E-CM ) with cultured human umbilical vein endothelial cells ( HUVEC ), resulted in a fivefold increased formation of thiobarbituric acid-reactive substances ( TBARS ) and activation of the transcription factor NF-kB , both indicators of cellular oxidant stress .
 cell line: HUVEC; protein: vWf; protein: transcription factor; cell type: SS RBC; cell line: cultured human umbilical vein endothelial cells; protein: von Willebrand factor; protein: NF-kB; cell type: endothelial cells
