Fig. 3From: Tubularized urethral reconstruction using everted saphenous vein graft in a beagle modelHistological and IHC analysis. a–d HE staining, MT staining, IHC staining with UP-II and CD31 antibodies of the reconstructed urethra in normal group. e Wide urethral lumen was completely covered by endothelium in experimental group. f MT staining showed highly organized collagen fibers and muscle tissue in subepithelium. g IHC staining with UP-II antibody showed expression of uroplakin in the endothelium. h IHC staining with the CD31 showed dense capillaries in subepithelium. i HE staining showed a narrow urethral lumen and urothelium defect in control group. j MT staining showed fibrosis with abundant collagen. k IHC staining with the UP-II revealed a fragment of urothelium. l Vascular capillaries were sparse in control groupBack to article page
