These results confirmed the importance of COX-2/PGE2 in the healing mechanism of gastric ulcers and further suggested that the healing-promoting action of PGE2 is mediated by the activation of EP4 receptors and is associated with VEGF expression.
Although both aspirin and ticlopidine markedly suppressed platelet aggregation, only ticlopidine impaired gastric ulcer healing and angiogenesis as well as reversing the ulcer-associated changes in serum levels of VEGF and endostatin.

During gastric ulcer healing, MMP-2, MMP-3, and MMP-13 RNA expression was increased in stromal cells of the gastric mucosa bordering the ulcer, suggesting a prevalent role of non-epithelial cells in pericellular proteolysis.
