Abstract

We regret the misspelling of several author names in this article. The correct names of the authors are: Rainer Moog, MD, PhD, Thomas Zeiler, MD, Hans-Gert Heuft, MD, Bernhard Stephan, MD, Eike G. Fischer, PhD, Volker Kretschmer, MD, PhD, Regina Rödel-Spiecker, Erwin Strasser, MD, and Jürgen Zingsem, MD. July Cover We regret that the term of Thomas F. Zuck, MD, JD as Editor-in-Chief of TRANSFUSION was incorrectly stated. Dr. Zuck was the Editor of TRANSFUSION from 1981 until 1987. We sincerely apologize for this error. Strasser EF, Berger TG, Weisbach V, Zimmermann R, Ringwald J, Schuler-Thurner B, Zingsem J, Eckstein R. Comparison of two apheresis systems for the collection of CD14+ cells intended to be used in dendritic cell culture. Transfusion 2003; 43:1309-16. The names of the apheresis devices were confused on page 1310. The corrected text is shown below, with the apheresis devices in bold. A total of 50 leukapheresis procedures obtained by Spectra were enrolled in this study. We applied a modified MNC program using a reduced separation factor (SF) of 250 (Cobe Spectra: MNC version 5.1).11,12 The inlet blood flow was 50 mL per minute with a continuous collection rate (CR) of 1.0 mL per minute. The anticoagulant ACD-A (Fresenius) was set to an ACD-A to blood ratio of 1 in 10 as basic adjustment for all procedures that varied depending on citrate reactions. The SF of 250 was equivalent to a centrifugation speed of 646 rpm at this flow rate. The rate of the plasma pump was set manually by visual inspection of the cell interface visible in the separation chamber and the observation of the collection line to target a Hct of approximately 5 percent. A total of 30 leukapheresis procedures were performed with a modified MNC program of the Astec device (Fresenius NPBI) using a single-stage separation chamber (P1Y tubing set) and the software (Fresenius ASTEC 204: MNC, version 1.1.6.3).12 All procedures were conducted following the manufacturers’ recommendations.
