Comparison of two continuous-flow systems for the collection of peripheral progenitor cells

Abstract

New advances in apheresis technology allow for the safe and efficient collection of peripheral progenitor cells (PPC). Two blood cell separators were compared with respect to separation results such as PPC yield and contamination of the products. A total of 11 patients (6 multiple myeloma, 4 non-Hodgkin lymphoma, and 1 medulloblastoma) underwent PPC collections with either the Amicus (Baxter) or AS. TEC (Fresenius) blood cell separator. PPC were mobilized by chemotherapy and granulocyte colony-stimulating factor (G-CSF) application. Blood counts were determined before and after apheresis as well as in the PPC product. CD34 antigen-expressing cells were measured in the peripheral blood and in the PPC product by flow cytometry. Median baseline CD34 antigen-expressing cells were higher in patients undergoing PPC collection with the Amicus device. More PPC/kg of body weight were collected with this machine (5.3 x 10(6)/kg body weight versus 1.7 x 10(6) in the AS. TEC). The median volume was 129 ml (range 80-156 ml) for Amicus products and 111 ml (range 66-202 ml) for the AS. TEC, respectively. The median platelet contamination of the products from the Amicus blood cell separator was significantly lower than in products from the AS....Continue Reading

Blood And Marrow Transplantation

The use of hematopoietic stem cell transplantation or blood and marrow transplantation (bmt) is on the increase worldwide. BMT is used to replace damaged or destroyed bone marrow with healthy bone marrow stem cells. Here is the latest research on bone and marrow transplantation.

B-Cell Lymphoma

B-cell lymphomas include lymphomas that affect B cells. This subtype of cancer accounts for over 80% of non-Hodgkin lymphomas in the US. Here is the latest research.
