Automated preparation of washed platelet concentrates through spinning-membrane filtration.

Background: Washed platelet concentrates (WPC), prepared with an automated system cell processor (ACP), have recently been approved to be manufactured and marketed in Japan. From the perspective of risk management, it is preferable to secure alternative technologies for ACP. Here, we conducted a study to evaluate the quality of WPC prepared using an automated membrane filtration-based system, Lovo.

Comparison of the programmed freezer method and deep freezer method in the manufacturing of frozen red blood cell products.

Background And Objectives: Frozen-thawed red blood cells (FTRCs) are useful blood components to patients with rare blood phenotypes. However, frozen red blood cells (FRCs) sometimes cause significant haemolysis after thawing due to the freeze/thaw process. In this study, we aimed to focus on the former process and reduce process-related haemolysis.
