Allogeneic donor peripheral blood “stem cell” apheresis: prospective comparison of two apheresis systems

BACKGROUND: Granulocyte–colony‐stimulating factor–mobilized peripheral blood stem cells, collected by white blood cell apheresis, are used for more than 80% of allogeneic and most autologous hematopoietic stem cell transplantations. Optimal donor and recipient outcomes require maximized stem cell collection efficiency and minimized non–target cell contamination. Therefore, improved apheresis technology is desirable. The safety and feasibility of...
