Microparticle (MP) count in red blood cell units during storage (without centrifugation).
Data are expressed as the mean±SD (n=7). At day 5: 3,371±1,188 MPs/μL were counted, whereas at day 50: MPs had approximately 20-fold (64,858±37,846 MPs/μL). MPs were stained with anti-human CD47. (Adapted with permission from Rubin et al.,71).
