Angiogenesis is the growth of new blood vessels. In the two major forms of inflammatory bowel disease (IBD), Crohn's disease and ulcerative colitis, robust angiogenesis exists, and its blockade may have therapeutic potential, as shown in animal models of experimental intestinal inflammation. While abundant literature is available on the positive regulators of intestinal pathological angiogenesis, e. g. VEGF, bFGF, IL-8, CD40 and CD40L, almost no data exist on negative regulators. Thrombospondin-1 is a negative regulator of angiogenesis, and it plays a new role in IBD-associated angiogenesis. In addition, recombinant thrombospondin-1 may inhibit pathological angiogenesis and may offer a new therapeutic approach to intestinal inflammation. Copyright (c) 2008 S. Karger AG, Basel

Abstract
Angiogenesis is the growth of new blood vessels. In the two major forms of inflammatory bowel disease (IBD), Crohn's disease and ulcerative colitis, robust angiogenesis exists, and its blockade may have therapeutic potential, as shown in animal models of experimental intestinal inflammation. While abundant literature is available on the positive regulators of intestinal pathological angiogenesis, e. g. VEGF, bFGF, IL-8, CD40 and CD40L, almost no data exist on negative regulators. Thrombospondin-1 is a negative regulator of angiogenesis, and it plays a new role in IBD-associated angiogenesis. In addition, recombinant thrombospondin-1 may inhibit pathological angiogenesis and may offer a new therapeutic approach to intestinal inflammation. Copyright (c) 2008 S.
