## Abstract Optimal collections of mobilized CD34+ cells are important in terms of both patient toxicity and cost. The factors that determine CD34+ collection efficiency (CD34eff) of cell separators have not been well studied. In addition, because several cell separators are available, the type of

β¦ Synopsis
Hematopoietic stem cells, collected by leukapheresis from peripheral blood. can be used as an alternative to autologous bone marrow transplantation following high-dose chemotherapy as treatment of several malignancies. We compared the ability of the Cobe Spectra and the Fenwal CS3000 to collect peripheral blood mononuclear cells (MNC) for autologous peripheral blood stem cell transplantation. Ten patients experienced repeated leukapheresis (10 L blood processed per procedure) using both instruments. Procedures were alternated between the two until a total of 7 x 10' MNCikg was collected. Data from 61 Spectra and 50 CS3000 collections were analyzed. The yield (mean per procedure) of nucleated cells (NC) and MNC was higher ( P < ,005) with the Spectra (0.77 X 10'" NC and 0.54 x 10'" MNC) than with the CS3000 (0.59 X 10" NC and 0.40 X 10" MNC). However, colony forming units (CFU-GM) were not different (P > .05) for Spectra (0.92 X lo4) and Fenwal (0.65 X lo4) collections. Platelet contamination was lower ( P < ,001) with the Spectra (2.2 X 10") than the CS3000 (5.0 X 10"). This correlated with a higher patient blood platelet count immediately following Spectra collections (1 17 X 109/L) versus the CS3000 (86 X 109/L). Using the methods described. the Spectra product contained greater yields of NC and MNC with less platelet contamination than did the CS3000.
