TSP-1 was sporadically found (4 cases, expression within intestinal epithelium, see Figure 9) only in samples from patients with IBD (3 in CU and 1 in CD), and it seems to be rather artifactual and insufficient to make any statistical correlation between TSP-1 expression and vascular density or VEGFR-1 expression. Here, THBS1 is linked to inflammatory bowel disease.
