RESUMO
This study was aimed to investigate the changes of cytokine contents in single donor platelets (SDPs) collected by using MCS(+), Trima, Amicus blood cell separators during storage. 18 portions of SDPs were collected by MCS(+), Trima, Amicus blood cell separators, were preserved in standard condition of blood bank, the levels of cytokines such as IL-8, RANTES, CD154, TGF-beta(1) and VEGF were detected by ELISA at 1, 3, 5, 7 days during storage. The results showed that the levels of IL-8, RANTES, CD154, TGF-beta(1) and VEGF in SDPs collected by blood cell separators MCS(+), Trima, and Amicus gradually increased with prolonging of time during storage, but the increase of IL-8 level in SDPs collected by MCS(+) separator was significant difference from SDPs collected by Trime and Amicus separators (p < 0.05). It is concluded that the all collected SDPs mentioned above express IL-8, RANTES, CD154, TGF-beta(1) and VEGF during storage, and their cytokine levels show a tendency to increase with prolonging of time during storage, apheresis platelets with less leukocytes express IL-8 lower.
