Abstract
Peripheral blood is the prefered source for hematopoietic stem cells for hematopoietic stem cell transplantation. The efficiency of peripheral blood stem cell (PBSC) collection can vary among devices. In this study we aimed to compare feasibility and effectivity of apheresis procedures of the different systems. Two apheresis systems [Com.Tec (Fresenius Healthcare) and Spectra Optia (Caridian BCT)] were used in our center for the collection of PBSCs for autologous and allogeneic transplantation. We retrospectively analysed 190 apheresis procedures performed in healthy donors and patients between June 2012 and November 2014 in Department of Hematology, Dokuz Eylul University. PBSCS were collected by Fresenius cell separator (64 procedure) or Spectra Optia cell separator (126 procedure). Mobilization treatments were G-CSF (26.8%), cyclophosphamide plus G-CSF (48.4%), prelixafor plus G-CSF (14.7%), ESHAP (10%) and others. Patient and donor characteristics (age, weight, volume processed, disease, mobilization regimes) were similar in Fresenius and Spectra Optia apheresis groups. Altough both collected PBSCs efficiently, the amount of CD34+ cell in product collected by Spectra Optia device was significantly higher (p < 0.05) and product volume was lower than Fresenius Com.Tec significantly (p < 0.05). "CD34+ collection efficiency" with Spectra Optia was significantly higher than Fresenius Com.Tec (CE2: 87%, 70%, p = 0.033) regarding all procedures. High collection efficiency and low product volume may be a significant characteristic of Spectra Optia device (mean 187 mL, product CD34+ cell: 1576 µL).

Abstract
In this study, we aimed to investigate whether the procedure and product kinetics differ according to age groups in advanced-age MM patients who underwent autologous HSCT. 59 patients who underwent autologous HSCT were retrospectively analyzed. Then, the patients were divided into two groups as 60-65 years and ≥65 years. It was significantly lower in ≥65 years group (p = 0.008) and proportionally, the procedure duration was also significantly shortened in this group (p = 0.013). Total number of collected CD34 positive stem cells was 6.20 × 106 (±3.83) in 60-65 years group while it was 5.51 × 106 (±2.48) in ≥65 years group with no statistically significant difference (p = 0.825). In conclusion, there was no significant difference in terms of the number of collected CD34-positive stem cells in this study that investigates the mobilization data, procedure and product kinetics, we think that successful stem cell mobilization can be performed in appropriately selected patients regardless of age.

Abstract
Hematopoietic stem and progenitor cell (HSPC) transplantations require prior harvesting of allogeneic or autologous HSPCs. HSPCs are usually present in bone marrow (BM) during the entire life, in cord blood (CB) at birth, or in peripheral blood (PB) under particular circumstances. HSPCs were first harvested in BM and later in CB and PB, as studies showed interesting features of such grafts. All harvesting methods were in use throughout the years, except BM harvesting for HSPC autologous transplantation, which was replaced by PB harvesting. BM, CB, and PB harvesting methods have been developed, and materials and devices technically improved to increase the number of HSPCs harvested. In parallel, knowing the features of the donors or patients associated with successful numbers of HSPCs allows the adaptation of appropriate harvesting methods. Moreover, it is important to ensure the safety of donors or patients while harvesting. This review describes the methods used for harvesting based on recent studies or developments around these methods, and more particularly, the means developed to increase the numbers of HSPCs harvested in each method. It also explains briefly the influence of technical improvements in HSPC harvesting on potential changes in HSPC graft composition.

Abstract
BACKGROUND This study was conducted to evaluate the performance of the COM.TEC cell separator (Fresenius HemoCare GmbH) for collecting CD34+ cells in pediatric patients who were intended to have autologous peripheral blood progenitor cell transplantation, with respect to collection variables, prediction power of CD34+ cell yield, and influence on donors. STUDY DESIGN AND METHODS A total of 26 pediatric solid tumor patients who received mobilization chemotherapy and granulocyte-colony-stimulating factor underwent CD34+ cell collection (n = 96) using the COM.TEC auto mononuclear cell (MNC) program. Patients were divided into a neuroblastoma (NBL) group and a brain tumor group according to the intensity of prior chemotherapy regimens. The collection variables, cellular variables of leukapheresis products, and the peripheral blood cell counts of patients were compared with those acquired using the COBE Spectra (GambroBCT). The CD34+ cell collection efficiency (CE) and the percentage ratios of actual to predicted CD34+ cell yield indicating prediction power were analyzed. RESULTS Using the COM.TEC auto MNC program, the processing rate was higher and the product volume was smaller (p < 0.05) than those of the COBE Spectra. Platelet (PLT) reduction in peripheral blood and PLT contamination of the products were significantly lower (p < 0.01). The median CE was less than 60% in both patient groups (50.0 and 48.4%, respectively). The actual collected CD34+ cell yields were medians of 66.9 and 76.1% of the predicted values in NBL group and brain tumor group, respectively. CONCLUSION PBPC collections by the COM.TEC cell separator had advantages of high processing rate, low product volume, and low contamination by PLTs of product. Low PLT loss was observed in pediatric patients who need to collect autologous PBPCs. However, applying CD34+ cell yield prediction was not practical for prospective scheduling of the next collection. More specified data need to be accumulated for more accurate prediction of CD34+ cell yield in pediatric patients.

Abstract
Leukapheresis is the method of choice to collect monocytes for dendritic cell (DC) culture. Improvement of cell separators and cell collection software have enabled the collection of 10(9) monocytes for the generation of monocyte-derived DCs, which is sufficient to prepare a DC vaccine series. However, leukapheresis works with the technique of differential centrifugation which is not applicable to selectively collect mononuclear cells of similar density. After leukapheresis, thus, additional preparation steps are required to isolate and enrich the desired monocyte population. The cell isolation and cultivation techniques depend on the quality of the original leukocyte harvest due to the monocyte yield and the content of residual erythrocytes and platelets. Monocyte elutriation from the leukapheresis product shows a high monocyte recovery of 80%. However, only 30% of the isolated monocytes can be developed into mature DCs. The factors responsible for DC maturation and the development of different DC subsets are the subject of current research.
