Allogeneic peripheral blood stem cell (APBSCs) transplantation is an effective treatment for hematological malignancies. However low-weight donor children meet some complications. In the current report, PBSCs were harvested from a 14-month-old child (9.8Kg) for a 6years old sibling recipient suffering from pre-B type of acute lymphoblastic leukemia (ALL) and also 24 months old male child donor (12Kg) for a haploidentical recipient suffering from acute myeloid leukemia (AML-M4EO). The PBSC harvesting was performed using Spectra™ Optia(®) apheresis software with continuous mononuclear cell (CMNC) procedure...

In contemporary clinical practice, almost all allogeneic transplantations and autologous transplantations now capitalize on peripheral blood stem cells (PBSCs) as opposed to bone marrow (BM) for the source of stem cells. In this context, granulocyte colony-stimulating factor (G-CSF) plays a pivotal role as the most frequently applied frontline agent for stem cell mobilization. For patients classified as high-risk, chemotherapy based mobilization regimens can be preferred as a first choice and it is notable that this also used for remobilization...

Mobilization of hematopoietic stem cells, which has largely replaced bone marrow harvesting as a source of hematopoietic stem cells, using recombinant agents such as filgrastim or lenograstim has become a standard procedure in both patients and healthy donors prior to peripheral blood stem cell collection for autologous and allogeneic stem cell transplantation. Published literature data suggest that mobilization with recombinant granulocyte-colony stimulating factor (G-CSF) is safe and mobilization outcomes are satisfactory...

In order to decrease donors' exposure to granulocyte-colony stimulating factor (G-CSF), we compared the effect of two versus three days of G-CSF priming on CD34+ yield in bone marrow (BM) harvest. Although the number of BM-CD34+ cells was higher in 3day G-CSF priming, we achieved the same number of CD34+ cells per recipient's weight in 2day G-CSF priming group, too. In addition, the number of total nucleated cells (TNC) harvested from BM were similar with two or three day regimen. But mononuclear cells (MNC) of the BM graft was higher in the 3day G-CSF priming group...

Mobilization of hematopoietic stem and progenitor cells (HSPCs) from the bone marrow (BM) into the peripheral blood is a complex process that is enhanced dramatically under stress-induced conditions. A better understanding of how the mobilization process is regulated will likely facilitate the development of improved clinical protocols for stem cell harvesting and transplantation. In this issue of the JCI, Singh et al. (1) showed that the truncated cleaved form of neurotransmitter neuropeptide Y (NPY) actively promotes a breach of BM vascular sinusoidal portals, thereby augmenting HSPC trafficking to the circulation...

Peripheral blood stem cell mobilization with cytokines for autologous stem cell transplant in multiple myeloma is adversely affected by initial induction therapy consisting of either Lenalidomide or cytotoxic drugs, with failure rates of up to 45%. The use of Plerixafor with G-CSF for PBSC mobilisation significantly improves the chances of a successful mobilization. Plerixafor is a costly therapy and increases the overall costs of ASCT which can affect the number of patients being taken up for ASCT in resource limited settings...

In this randomized controlled trial, in early osteoarthritis (OA) that failed conservative intervention, the need for total knee arthroplasty (TKA) and WOMAC scores were evaluated, following a combination of arthroscopic microdrilling mesenchymal cell stimulation (MCS) and repeated intra-articular (IA) autologous activated peripheral blood stem cells (AAPBSCs) with growth factor addition (GFA) and hyaluronic acid (HA) versus IA-HA alone. Leukapheresis-harvested AAPBSCs were administered as three weekly IA injections combined with HA and GFA (platelet-rich plasma [PRP] and granulocyte colony-stimulating factor [hG-CSF]) and MCS in group 1 and in group 2 but without hG-CSF while group 3 received IA-HA alone...

The first clinical trials of cell therapy in stroke were first published in the 2000s and consisted of neural stems cells transplanted via the intracerebral pathway. Since mesenchymal stem cells showed similar capacities to differentiate into neural cells and allowed autologous cell transplantation, they were then preferentially studied, including diabetes and hypertension. More recently, bone marrow derived mononuclear cells were successfully transplanted in stroke with no need of culture processing, and simple collection by density gradient centrifugation rendering them immediately ready for use...

Donor mesenchymal stem cells (MSCs) could prolong vascularized composite allotransplantation (VCA) survival in our previous studies. However, recipient adipose tissue is easier to harvest than donor tissue for preconditioning modulation. Hence, this study investigated the efficacy of recipient autologous adipose-derived stem cells (rADSCs) for VCA survival. The heterotopic hind-limb transplantation from female donor to male recipient was performed in outbred miniature swine. Group I ( n = 6) was untreated controls...

OBJECTIVES: Bone marrow harvesting is one of the essential sources of stem cells for hematopoietic stem cell transplantation. We describe here the current "up-to-date" standard of the bone marrow harvest in unrelated stem cell donors. METHODS: We analyzed medical data of 187 unrelated hematopoietic stem cell donors who underwent bone marrow harvest without previous peripheral blood stem collection at the center between 2011 and 2015. The methodology of marrow collection includes multiple cells aimed at safety of the procedure, for example, educational movie, modified skin disinfection protocol, cell enumeration during the procedure, reduction of the contamination surfaces, and ongoing monitoring of the quality of work of the doctors...

Many hematologic malignancies are diseases of aging, and the use of hematopoietic cell transplant (HCT) is growing rapidly among older adults. Modern post-transplant cyclophosphamide (PTCy) protocols with haploidentical (haplo) donors have dramatically expanded the donor pool for patients requiring HCT. Initial studies were performed with bone marrow grafts, which require the donor to undergo anesthesia during harvest. However, the use of mobilized peripheral blood stem cells (PBSCs) may be desirable, especially with older donors...

BACKGROUND: CD34 flow cytometry is the gold standard for stem cell enumeration in peripheral blood at the mobilization stage and in the final apheresis product. The new stem cell mode of the Sysmex XN Series analyzer enumerates an immature cell population in the white progenitor and pathological cell (WPC) channel, based on the cell size, internal cellular complexity, and fluorescence intensity. STUDY DESIGN AND METHODS: In this multicenter study we analyzed 147 peripheral blood samples, 22 samples during collection of stem cells, and 45 samples from the apheresis product of 18 healthy allogeneic donors and 84 autologous patients...

Plerixafor is a CXC chemokine receptor (CXCR4) antagonist that mobilizes stem cells in the peripheral blood. It is indicated (in combination with granulocyte-colony stimulating factor [G-CSF]) to enhance the harvest of adequate quantities of cluster differentiation (CD) 34+ cells for autologous transplantation in patients with lymphoma or multiple myeloma whose cells mobilize poorly. Strategies for use include delayed re-mobilization after a failed mobilization attempt with G-CSF, and rescue or pre-emptive mobilization in patients in whom mobilization with G-CSF is likely to fail...

Autologous haematopoietic stem cell transplantation (AHSCT) remains recommended treatment in the first remission in multiple myeloma (MM). In earlier research it has been suggested that there is an influence of the expression of dipeptidyl peptidase-4 (CD26) on both the homing and lymphocyte reconstitution after AHSCT. The aim of the study is to investigate the influence of transplanted cells CD26+ on the haematopoietic recovery and lymphocyte reconstitution after AHSCT in MM. Forty eight patients with MM underwent AHSCT in our centre...

BACKGROUND: Peripheral blood stem cells mobilized with granulocyte-colony-stimulating factor (G-CSF) with or without chemotherapy are routinely used for autologous hematopoietic cell transplantation. Plerixafor, a chemokine-receptor inhibitor, increases the amount of circulating CD34+ cells and improves harvest results. However, limited information is available regarding the composition of apheresis products with respect to CD34+ and lymphocyte subtypes collected after various mobilization regimens...
