Figure 9 Reduction of inflammatory angiogenesis after chronic colitis induction in CD40KO and CD40LKO mice. Colonic sections were established from either wild‐type (WT) or CD40 knockout (CD40KO) or CD40L knockout (CD40LKO) mice, after development of chronic dextran sodium sulphate (DSS)‐induced colitis.31 Microvessel density was used as an indicator of angiogenesis. *p<0.01 when comparing either CD40KO (n = 8) or CD40LKO (n = 7) mice with their WT counterpart (n = 7).
