Platelet factor 4 in platelet concentrates.

Journal of the Japan Society of Blood Transfusion, 1984
The release of platelet factor 4 (PF4) from platelets in platelet concentrates (PC) were investigated sequentially in the process of blood collection, and their storage at room temperature for up to 72h with agitation. No appreciable increase in PF4 release was seen immediately after blood collection.

The Effect of Leukocyte Removal and Matrix Metalloproteinase Inhibition on Platelet Storage Lesions

Cells
The reasons for unfavorable changes in platelet concentrate (PC) quality during storage are not fully understood yet. We aimed to evaluate whether leukocytes and matrix metalloproteinases (MMPs) lead to a decrease in the quality of PCs and examine ...
