Harvesting of CD34 antigen-expressing cells with a new programme for the collection of mononuclear cells with use of the Amicus (Baxter) blood cell separator.

摘要

A study was performed to evaluate a new programme for peripheral blood stem cell (PBSC) collection with the use of the Amicus (Baxter) blood cell separator. Healthy donors (n = 9) and oncology patients (n = 21) scheduled for PBSC transplant were studied. Ten PBSC harvests were performed in the donors and 30 in the patients. A median of 6.37 x 106 CD34+ cells per kg recipient body weight (range 3.08-11.06 x 106) were collected from the donors in a product weight of 169.5 g (118-186). From the patients, 6.26 x 106 CD34+ cells per kg body weight (range 0.2-53.6 x 106) were harvested in a product weighing 121.5 g (range 92-190). The median platelet contamination was 0.93 x 1011 (range 0.45-1.23 x 1011) per donor product and 0.2 x 1011 (range 0.05-0.86 x 1011) per patient product. No severe side effects were observed during or after the PBSC collection procedures.
