Abstract/OtherAbstract:
A rabbit model was developed to study the in vivo viability of neutrophils stored in vitro for up to 72 h. Acid-citrate-dextrose anticoagulated whole blood was obtained from rabbits previously injected with tritiated thymidine ([3H]thymidine), stored under varying conditions, and then injected into recipient rabbits. Neutrophil viability and function were assessed by measuring the ability of the tagged neutrophils to circulate and to migrate into subcutaneous polyvinyl sponges. Unstored neutrophils disappeared exponentially from the circulation with a t1/2 of 3.2 h and gave a zero time recovery of 30.5%. Storage of cells at either room temperature or 4 degrees C for 24 h or longer resulted in temporary sequestration of cells from active circulation. With cells stored for up to 72 h at 4 degrees C, recovery returned to normal values after 1-2 h. Room temperature stored cells, in contrast, showed evidence of irreversible damage at 48-h storage with low recovery for the entire time span studied. With unstored blood, 8.1+/-0.9% of the injected neutrophil label was present in the subcutaneous sponges. The accumulated label progressively decreased as cell storage time increased reaching at 72 h 5.1+/-0.6 and 2.6+/-0.3% for 4 degrees C and room temperature-stored cells, respectively. The results of this study indicate that 4 degrees C storage of rabbit neutrophils is superior to storage at room temperature. The data suggest that it may be feasible to store neutrophils at least a few days without loss of in vivo functions.
