It has also been reported that tumour stromal fibroblasts are necessary for steps in cancer progression, such as angiogenesis. There have been few reports of a correlation between(More)
VEGF is a highly specific stimulator of endothelial cells and may play an important role in angiogenesis in the process of tissue regeneration. We previously showed that cyclooxygenase-2 (COX-2) expressed in mesenchymal cells of the ulcer bed is involved in the ulcer repair process. To clarify the role of COX-2 in angiogenesis during gastric ulcer healing,(More)
