[Retracted] Influence of P(VDF-TrFE) Membranes with Different Surface Potentials on the Activity and Angiogenic Function of Human Umbilical Vein Endothelial Cells

Figure 6

Effects of P(VDF-TrFE) membranes with differential surface potentials on tube formation. (a) The representative images showed the effect of P(VDF-TrFE) membranes with differential surface potentials on the angiogenic ability of HUVECs. (b) Relative tube formation and master segments length were quantified by ImageJ software. A one-way ANOVA is used to analyze the data that come from three independent tests (). , , , and .
