Analysis reveals receptor decline and RNA loss in platelet concentrates during storage, implying monitoring strategies may enhance quality.

To characterize alterations in platelet surface receptors and RNA content during storage to understand platelet storage lesion mechanisms.
Prepared platelet-rich plasma and platelet-poor plasma from healthy donors.
Used flow cytometry to assess receptor expression and Thiazole orange staining for RNA content.
Quantified soluble GPVI levels by ELISA and analyzed data using one-way ANOVA and Student’s t-test.
Stored platelet concentrates displayed significant decline in GPIbα and GPVI expression after day 6.
αIIbβ3 expression decreased early with stabilization, while CD9 expression remained unchanged.
Thiazole orange staining indicated a gradual loss of RNA-rich platelets, signaling aging.
Increased soluble GPVI levels were observed, inversely correlating with surface GPVI loss.
