Immunopathology of mutant (cd39^−/−) accommodated cardiac xenografts. (A) Hematoxylin and eosin-stained section; (B) cd39-stained section; (C) P-selectin stain. Representative fields from accommodated mutant xenografts at 60 days after transplantation show patchy myocardial injury with deposition of platelets within the vasculature as demonstrated by the P-selectin staining. No reaction for vascular cd39 is noted, as anticipated.
