Figure 1.

Graph showing area increase (mm²) of an endothelial cell line (growth by vascular mimicry) after supplementation with stored blood transfusion packed red cell products (pre-incubated with anti-endothelial growth factor antibodies). There was a significant difference between growth of control samples and cell lines supplemented with supernatant from blood transfusion products (p < 0.001) as well as a significant difference between the effect of pre-incubation of supernatant with anti-endothelial growth factor antibodies on cell line growth (p < 0.001) with control and pure supernatant samples.
