TCP1 and Chronic colitis: In our study, we found that TCP-1 peptide could not recognize the neovasculature of acute and chronic colitis in mice induced by dextran sulfate sodium (DSS) though chronic inflammatory bowel diseases are directly related to colorectal cancers (unpublished data), suggesting the binding site of TCP-1 peptide in the blood vessels is a marker for tumors but not for inflammatory tissues in the same organ.
