Figure 1 (a) Flow changes after ligation of the caudal and central arteries of the rabbit ear: flow recovery stabilizes after three weeks and is maintained at <70% of control for at least two months. (b) Western blot showing increased vascular endothelial growth factor (VEGF) expression in hypoperfused tissues two months after ligation. (c) Western blot showing angiopoietin-1 (Ang-1) expression in tissues where adenovirus-encoding Ang-1 gene (Ad.Ang-1) was injected.
