Increased transforming growth factor β contributes to deterioration of refrigerated fresh frozen plasma's effects in vitro on endothelial cells.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Resuscitation with fresh frozen plasma (FFP) is associated with improved outcomes after hemorrhagic shock. Many trauma centers are using thawed plasma that has been stored for up to 5 days at 4°C (refrigeration), yet the effect of refrigeration on FFP is relatively unknown. Previously, our group showed that refrigeration of FFP changed its coagulation factors and diminished its beneficial effects on endothelial cell (EC) function and resuscitation in an animal model of hemorrhagic shock. We hypothesize that growth factor composition of FFP is altered during refrigeration, leading to a diminished beneficial effect on EC. Transforming growth factor (TGF-β) is a potent inhibitor of EC migration and is released during refrigeration of platelets. We found increased TGF-β1 protein levels and greater activation of downstream mediators Smad2/3 during refrigeration of FFP. Both day 0 FFP (used on the same day after being thawed) and day 5 FFP (used after being thawed and refrigerated for 5 days) stimulated EC migration in vitro; however, the EC migration in day 5 FFP was significantly reduced. Inhibition of TGF-β type I receptor blocked FFP-induced Smad3 signaling in EC cells and restored the effectiveness of day 5 FFP on EC migration to a comparable level seen in day 0 FFP. These data suggest that the increased TGF-β levels during FFP refrigeration contribute to the deterioration of refrigerated FFP's effects on EC migration. This study identifies a novel molecular mechanism contributing to the reduced efficacy of refrigerated FFP.
