Figure 1

(a) ‘Normal’ grade (Ferguson & Parrott 1973) foetal intestinal mucosa. Mucosal architecture is preserved. 129SV−/− graft→129SV−/− host. 9 days post implantation. Original magnification ×400. (b) ‘Flat’ grade (Ferguson & Parrott 1973) enteropathy with subtotal villous atrophy. There is loss of villi and lengthening of crypts. 129SV−/− graft→Balb/c host. 9 days post implantation. Original magnification ×400. (c) ‘Submucosa’ grade (Ferguson & Parrott 1973) enteropathy with complete mucosal destruction. Necrotic tissue is seen overlying the muscularis mucosa. 129SV+/+ graft→Balb/c host. 5 days post implantation. Original magnification ×400.
