BACKGROUND: Biosimilar granulocyte colony-stimulating factor (G-CSF) has recently been introduced into clinical practice. G-CSFs are used to mobilize CD34(+) cells and accelerate engraftment after transplantation. However, in Asia, particularly in Japan, data for peripheral blood stem cell (PBSC) mobilization by this biosimilar G-CSF are currently lacking. Therefore, the clinical efficacy and safety of biosimilar G-CSF for hematopoietic stem cell transplantation needs to be evaluated in a Japanese context...

Peripheral blood stem cells (PBSCs) used for allogeneic transplantation are collected by apheresis after pre-treatment of donors with G-CSF. Using modern apheresis devices stem cells can be collected more efficiently. It was studied whether collection on the 4th instead of the 5th day after initiation of G-CSF treatment might be feasible. Stem cell yields that could have been collected on day 4 were calculated in two cohorts treated with 10 µg/kg G-CSF once daily (n = 106, cohort I) or 5 µg/kg twice daily schedule (n = 85, cohort II)...

Today, peripheral blood stem cells are the preferred source of stem cells over bone marrow. Therefore, mobilization plays a crutial role in successful autologous stem cell transplantation. Poor mobilization is generally defined as failure to achieve the target level of at least 2×10(6) CD34(+) cells/kg body weight. There are several strategies to overcome poor mobilization: 1) Larger volume Leukapheresis (LVL) 2) Re-mobilization 3) Plerixafor 4) CM+Plerixafor (P)+G-CSF and 5) Bone Marrow Harvest. In this review, the definitions of successful and poor mobilization are discussed...

BACKGROUND: Cyclophosphamide plus thalidomide as induction for multiple myeloma patients eligible for autologous stem cell transplantation may be a limiting factor for cell mobilization. The minimum acceptable mobilized peripheral blood stem cell count to prevent deleterious effects during transplantation is 2.0×10(6) CD34(+) cells/kg. Combining other treatments to granulocyte-colony stimulating factor, such as cyclophosphamide, could overcome the mobilization limitation. The objective of this study was to assess the number of CD34(+) cells mobilized using granulocyte-colony stimulating factor with and without cyclophosphamide after induction with cyclophosphamide, thalidomide and dexamethasone...

BACKGROUND: A second allogeneic hematopoietic stem-cell transplantation and donor lymphocyte infusion using cells from the same donor is a therapeutic option in the case of stem-cell graft failure or disease relapse, but little is known about the factors associated with the CD34(+) cell yields from second donations. METHODS: One-hundred healthy donors who underwent a second mobilization treatment and peripheral blood stem-cell (PBSC) collection were studied. For both mobilization processes, 5 µg of granulocyte colony-stimulating factor per kg per day was administered...

REVIEW
Frédéric Selle, Joseph Gligorov, Daniele G Soares, Jean-Pierre Lotz
The concept of high-doses chemotherapy was developed in the 1980s based on in vitro scientific observations. Exposure of tumor cells to increasing concentrations of alkylating agents resulted in increased cell death in a strong dose-response manner. Moreover, the acquired resistance of tumor cells could be overcome by dose intensification. In clinic, dose intensification of alkylating agents resulted in increased therapeutic responses, however associated with significant hematological toxicity. Following the development of autologous stem cells transplantation harvesting from peripheral blood, the high-doses of chemotherapy, initially associated with marked toxic effects, could be more easily tolerated...

Recently, we have reported that adipose tissue-derived stem cells (ASC) harvested from obese donors induce a pro-inflammatory environment when co-cultured with peripheral blood mononuclear cells (MNC), with a polarization of T cells toward the Th17 cell lineage, increased secretion of IL-1β and IL-6 pro-inflammatory cytokines, and down-regulation of Th1 cytokines, such as IFNγ and TNFα. However, whether differentiated adipocytes, like the aforementioned ASC, are pro-inflammatory in obese subject AT remained to be investigated...

We describe a 3D erythroid culture system that utilises a porous polyurethane (PU) scaffold to mimic the compartmentalisation found in the bone marrow. PU scaffolds seeded with peripheral blood CD34(+) cells exhibit a remarkable reproducibility of egress, with an increased output when directly compared to human bone scaffolds over 28 days. Immunofluorescence demonstrated the persistence of CD34(+) cells within the scaffolds for the entirety of the culture. To characterise scaffold outputs, we designed a flow cytometry panel that utilises surface marker expression observed in standard 2D erythroid and megakaryocyte cultures...

BACKGROUND: High-dose chemotherapy with autologous stem-cell transplantation (asct) is an accepted part of standard therapy for patients with hematologic malignancies. Usually, stem-cell mobilization uses granulocyte colony-stimulating factor (g-csf); however, some patients are not able to be mobilized with chemotherapy and g-csf, and such patients could be at higher risk of failing mobilization. Plerixafor is a novel mobilization agent that is absorbed quickly after subcutaneous injection and, at the recommended dose of 0...

: : Adult human peripheral blood mononuclear cells (hPBMCs) exhibit pluripotency in vitro and so may be a valuable cell source for regenerative therapies. The efficacy of such therapies depends on the survival, differentiation, migration, and integration capacity of hPBMCs in specific tissues. In this study, we examined these capacities of transplanted hPBMCs in mouse retina as well functional improvement after transplant. We isolated hPBMCs and preinduced them for 4 days in media preconditioned with postnatal day 1 rat retina explants...

Peripheral blood stem cells from healthy donors mobilized by granulocyte colony-stimulating factor (G-CSF) and harvested by leukapheresis are commonly used for allogeneic stem cell transplantation. The frequency of severe graft versus host disease is similar for patients receiving peripheral blood and bone marrow allografts, even though the blood grafts contain more T cells, indicating mobilization-related immunoregulatory effects. The regulatory phosphoprotein osteopontin was quantified in plasma samples from healthy donors before G-CSF treatment, after four days of treatment immediately before and after leukapheresis, and 18-24 h after apheresis...

BACKGROUND AND OBJECTIVE: Poor mobilization of peripheral blood stem cells (CD34(+) cells) from bone marrow is a frequent reason for not reaching the autologous stem cell trasplantation (SCT) procedure in patients diagnosed with lymphoma or myeloma. Plerixafor, a reversible inhibitor of the binding of stromal cell-derived factor 1 to its cognate receptor CXCR4, has demonstrated a higher capacity for the mobilization of peripheral blood stem cells in combination with granulocyte colony stimulating factor (G-CSF) compared with G-CSF alone...

The aryl hydrocarbon receptor (AHR) is a ligand-activated transcription factor belonging to the Per-Arnt-Sim (PAS) family of proteins. The AHR is involved in hematopoietic stem cell (HSC) functions including self-renewal, proliferation, quiescence, and differentiation. We hypothesize that AHR impacts HSC functions by influencing genes that have roles in HSC maintenance and function and that this may occur through regulation of bone marrow (BM) niche cells. We examined BM and niche cells harvested from 8-week-old AHR null-allele (KO) mice in which exon 3 was deleted in the Ahr gene and compared these data to cells from B6 control mice; young and old (10 months) animals were also compared...

The use of granulocyte colony-stimulating factor (G-CSF) primed bone marrow (G-BM) has been recently considered as an alternative to mobilized hematopoietic stem cells from peripheral blood (G-PB), especially in the haploidentical transplant setting. The purpose of this study was to compare the effect of in vivo G-CSF priming on BM and PB hematopoietic, mesenchymal (MSC), and immune cells. Forty healthy donors undergoing BM harvest for haploidentical transplant were given subcutaneous recombinant human G-CSF for 7 days...

BACKGROUND: Stem cell transplantation is an emerging method of treatment for patients with cardiovascular disease. There are few studies completed or ongoing on stem cell therapy in patients with idiopathic dilated cardiomyopathy (IDCM). Information on stem cell homing and distribution in the myocardium after transplantation might provide important insight into effectiveness of transplantation procedure. AIM: To assess early engraftment, retention and migration of intracoronarily transplanted stem cells in the myocardium of patients with advanced dilated cardiomyopathy of non-ischaemic origin using stem cell labeling with (99m)Tc-exametazime (HMPAO)...
