Renal mesenchyme dictates the identity of developing ureteric epithelium. Epithelia from the ureteric branches (A and G) or the ureteric stalk (C and E) were labelled with Rhodamine-conjugated Peanut agglutinin, isolated and transplanted into the metanephric mesenchyme (A,B and E,F) or the ureteric mesenchyme (C,D and G,H) of E11.5 kidneys. (A,C,E,G) show the position of transplanted epithelium (Red), with the approximate division between metanephric mesenchyme (MM) and prospective ureter mesenchyme (UM) annotated. (B,D,F and H) show development 5 days post transplantation: only grafts to peri-Wolffian mesenchyme become uroplakin-positive. UPK, Uroplakin. PCK, Pan-cytokeratin. Scale = 200 µm.
