In the article Intraportal pig islet xenotransplantation into athymic mice as an in vivo model for the study of the instant blood-mediated inflammatory reaction by M. Goto, C. Groth, B. Nilsson, and O. Korsgren, which appeared in the March/April 2004 issue of this journal, an incorrect figure was published. The correct Figure 1 should have been as follows:

Immunohistochemical staining of sections from grafted APIs after intraportal transplantation into diabetic athymic mice. The Figure shows the expression of insulin in grafts, the distribution of leukocytes, and the deposition of complement, IgG, and IgM after staining for insulin (A), CD11b (B), C3 (C), IgG (D), and IgM (E). The arrow indicates thrombus formation with entrapped porcine islets (A). Magnification × 100 in (A–E), and ×250 in small pictures inserted in (C–E).
