Fig. 3From: Platelet storage induces accelerated desialylation of platelets and increases hepatic thrombopoietin productionScanning electron microscopy (SEM) of the platelets at different storage durations and temperatures. Aged and refrigerated platelets showed morphologic changes including bulbous protrusions and pseudopods, indicating platelet activation.
