Effect of As2O3 on Matrigel-induced tube formation of HUVECs in vitro.
HUVECs (1 × 105 cells/well) were plated on growth-factor–reduced Matrigel in the presence of a culture medium. (A) Culture medium contained X-Vivo and endothelial cell growth supplement (ECGS). (B) Culture medium contained X-Vivo, ECGS, and VEGF (20 ng/mL). (C) Culture medium contained X-Vivo, ECGS, VEGF (20 ng/mL), and 5 × 10−7 mol/L As2O3. (D) Culture medium contained X-Vivo, ECGS, VEGF (20 ng/mL), and 5 × 10−6 mol/L As2O3.
