The major angiogenesis genes found to have significant expression differences (2-fold or greater difference and p-value of 0.01 or less) between mice undergoing a 50% proximal small bowel resection versus sham operation (bowel transaction with reanastomosis alone) at post-operative day 3 by RT2 Profiler PCR Array. These differences were verified by standard RT-PCR in separate reactions. Brain-specific angiogenesis inhibitor 1 (Bail), Chemokine (C-X-C Motif) ligand 5 (Cxcl5), Frizzled Homolog 5 (Drosophila) (Fxd5), Interleukin-lβ (Il 1b) and Placental growth factor (Pgf).
