The interaction between primate blood and mouse islets induces accelerated clotting with islet destruction

Abstract

Mouse islets induce rapid activation of the clotting cascade and platelet consumption in vitro when exposed to human blood, which correlated with histological evidence of significant destruction demonstrable within 1 h of exposure to human or non-human primate blood. This in vitro model has features which appear to correlate with the islet destruction seen in vivo and could be a useful model for the study of the mechanisms underlying the rapid destruction of xenogeneic islets in primate recipients.
