Abstract
Hydroxyethyl starch (HES) is used to separate hematopoietic progenitor cells after bone marrow (BM) collection from red blood cells. The aims were to study alternatives for HAES-steril (200 kDa; not available anymore) and to optimize the sedimentation process. Using WBC-enriched product (10 × 109 WBC/L), instead of BM, sedimentation at 10% hematocrit using final 0.6 or 0.39% Voluven (130 kDa) or without HES appeared to be good alternatives for 0.6% HAES-steril. MNC recovery >80% and RBC depletion >90% was reached. Optimal sedimentation was reached using 110–140 mL volume. Centrifugation appeared not suitable for sedimentation. Additional testing with BM might be necessary to confirm these results.
