Storage of red blood cells (RBCs) is necessary for an adequate blood supply. However, reports have identified potential negative sequelae of transfusing stored RBCs. An animal model would be useful to investigate the pathophysiology of transfusing stored RBCs. However, it has been reported that storage of rat RBCs in CPDA-1 resulted in an unexpected sudden decline in posttransfusion survival. A mouse model of RBC storage and transfusion was developed to assess survival kinetics of mouse RBCs. ⋯ Mouse RBCs showed a progressive decline in survival, as a function of storage time, unlike the precipitous loss of viability reported for rat RBCs. Moreover, changes in the measured surface markers were analogous to trends reported for human RBCs. Together, these findings provide an initial characterization of a novel mouse model of RBC storage with the potential to serve as an experimental platform for studying the pathophysiologic consequences of transfusing stored RBCs.
