摘要
Angiogenesis consists of the sprouting of capillaries from pre-existing vessels. It is well-known that tumor growth is angiogenesis-dependent. Vascular endothelial growth factor （VEGF） and basic fibroblast growth factor （bFGF） stimulated vascular endothelial cell proliferation and are involved in the neoplastic angiogenesis of several types of tumors including those of the intestinal tract. Authors usually investigated VEGF and using immunohistochemistry bFGF protein expressions or Western blotting and VEGF and bFGF transcripts using reverse transcriptase Dolymerase chain reaction （RT-PCR）.
TO THE EDITOR Angiogenesis consists of the sprouting of capillaries from pre-existing vessels . It is well-known that tumor growth is angiogenesis-dependent. Vascular endothelial growth factor (VEGF) and basic fibroblast growth factor (bFGF) stimulated vascular endothelial cell proliferation and are involved in the neoplastic angiogenesis of several types of tumors including those of the intestinal tract.Authors usually investigated VEGF and bFGF protein expressions using immunohistochemistry or Western blotting and VEGF and bFGF transcripts using reverse transcriptase polymerase chain reaction (RT-PCR). We recently reported in a previous issue of the World Journal of Gastroenterology that cirrhotic liver tissue levels of these two
