The 'epidemic' diffusion of chronic kidney disease (CKD) needs the development of new therapeutic approaches to slow down the progression to end-stage renal disease. Endothelial Progenitor Cells (EPCs) are promising tools for the treatment of many human diseases as they promote the repair of damaged tissues. They were also suggested as therapy to repair renal tissue after an injury. Strategies using EPCs to induce a reparative process with functional restoring of a diseased kidney or to delay CKD are of two types: direct stem cells infusion or stimulating endogenous release of EPCs...

BACKGROUND: We previously identified circulating mesoangioblasts (cMABs), a subset of mesenchymal stem cells that express cardiac mesodermal markers, in patients undergoing cardiac surgery with cardiopulmonary bypass (CPB). We also found that hepatocyte growth factor (HGF) is upregulated during cardiac surgery with CPB in humans, and induces MAB-like cell mobilization in rodents. These results strongly suggest that heparin induced MAB mobilization via HGF upregulation. Here, we tested this hypothesis in patients undergoing cardiac surgery or cardiac catheterization...

The extracellular matrix has drawn considerable interest in tissue engineering not only acts as a bioactive three-dimensional scaffold but also regulates cell behaviors through providing biochemical signals. Extracellular matrix-based biomaterials, mainly derived from xenogeneic tissues, have shown positive outcomes in promoting cutaneous wound healing. However, such extracellular matrices only contain low doses of growth factors, which limit their therapeutic efficiency. Recent reports demonstrated that cell sheets made from mesenchymal stem cell can accelerate wound repair through enhanced re-epithelialization and angiogenesis, but its clinical translation is hindered by several limitations, such as the risk of aberrant immune responses and cost implications...

Classical bone tissue engineering involves the use of culture-expanded cells and scaffolds to produce tissue constructs for transplantation. Despite promising results, clinical adoption of these constructs has been limited due to various drawbacks, including extensive cell expansion steps, low cell survival rate upon transplantation, and the possibility of immuno-rejection. To bypass the ex vivo cell culture and transplantation process, we exploited the regenerative capacity of the host by mobilizing endogenous stem cells to the site of injury...

INTRODUCTION: High-dose chemotherapy with autologous hematopoietic stem cell transplantation (auto-HSCT) improves the outcome of patients with multiple myeloma (MM). It seems that auto-HSCT is also a feasible therapeutic option in MM dialysis-dependent (MMDD) patients. However, to perform transplantation, a sufficient number of stem cells must be collected. MATERIALS AND METHODS: Given that data on mobilization of auto-HSC efficacy and safety in dialysis-dependent patients are limited, we report data from all Polish Centers belonging to the Polish Multiple Myeloma Group...

Several mechanisms have been postulated for orchestrating the mobilization of hematopoietic stem/progenitor cells (HSPCs), and we previously proposed that activation of the complement cascade plays a crucial role in the initiation and execution of the egress of HSPCs from bone marrow (BM) into peripheral blood (PB). In support of this notion, we demonstrated that mice deficient in the mannan-binding lectin (MBL) pathway, which activates the proximal part of the complement cascade, as well as mice deficient in the fifth component of the complement cascade (C5), which is part of the distal part of the complement cascade, are poor mobilizers...

BACKGROUND AIMS: Growing evidence supports the therapeutic potential of bone marrow (BM)-derived stem/progenitor cells for end-stage liver disease (ESLD). We recently demonstrated that CD133(+) stem/progenitor cell (SPC) reinfusion in patients with ESLD is feasible and safe and improve, albeit transiently, liver function. However, the mechanism(s) through which BM-derived SPCs may improve liver function are not fully elucidated. METHODS: Here, we characterized the circulating SPCs compartment of patients with ESLD undergoing CD133(+) cell therapy...

The C - X - C chemokine receptor 4 (CXCR4) and its natural ligand CXCL12 are key factors in the process of cell migration, homing of hematopoietic stem cells to the bone marrow, and represent important mediators of angiogenesis and cell proliferation. The CXCR4/CXCL12 interplay can be disrupted by CXCR4 antagonists such as Plerixafor which are already in daily clinical use, i.e. for mobilization and subsequent harvesting of hematopoietic progenitor cells and stem cell transplantation. In a pathological condition, involvement in the process of metastasis and homing of cancer cells to a protective niche has been described, making CXCR4 an attractive target for imaging and treatment of malignant diseases...

POEMS syndrome is a rare paraneoplastic condition, with a poorly understood pathogenesis. High dose chemotherapy followed by autologous stem cell transplantation (ASCT) has been reported to be an effective therapeutic option for patients with good performance status. Here, we review the role of ASCT for POEMS syndrome and discuss indications together with advantages and disadvantages, and related issues such lenalidomide given before or after ASCT, VEGF levels as a marker of disease, and different regimens for stem cell mobilization...

We evaluated usability of a previously developed genetically encoded molecular crowding sensor in various biological phenomena. Molecular crowding refers to intracellular regions that are occupied more by proteins and nucleotides than by water molecules and is thought to have a strong effect on protein function. To evaluate intracellular molecular crowding, usually the diffusion coefficient of a probe is used because it is related to mobility of the surrounding molecular crowding agents. Recently, genetically encoded molecular crowding sensors based on Förster resonance energy transfer were reported...

Gene targeting constitutes a new step in the development of gene therapy for inherited diseases. Although previous studies have shown the feasibility of editing fibroblasts from Fanconi anemia (FA) patients, here we aimed at conducting therapeutic gene editing in clinically relevant cells, such as hematopoietic stem cells (HSCs). In our first experiments, we showed that zinc finger nuclease (ZFN)-mediated insertion of a non-therapeutic EGFP-reporter donor in the AAVS1 "safe harbor" locus of FA-A lymphoblastic cell lines (LCLs), indicating that FANCA is not essential for the editing of human cells...

Current protocols for hematopoietic stem cell (HSC) gene therapy, involving the transplantation of ex vivo lentivirus vector-transduced HSCs into myeloablated recipients, are complex and not without risk for the patient. In vivo HSC gene therapy can be achieved by the direct modification of HSCs in the bone marrow after intraosseous injection of gene delivery vectors. A recently developed approach involves the mobilization of HSCs from the bone marrow into peripheral the blood circulation, intravenous vector injection, and re-engraftment of genetically modified HSCs in the bone marrow...

POEMS syndrome is a rare, chronic and disabling condition. The causes of this condition remain unknown; however, chronic overproduction of proinflammatory cytokines appears to be a major contributor. Early diagnosis is essential to start treatment before the clinical state of the patient becomes compromised. A complete evaluation of the disease at its onset is critical to the treatment decision. In localized disease, curative doses of radiation (50 Gy) is the recommended therapy. On the other hand, patients with disseminated disease should be given systemic therapy...

BACKGROUND: The addition of the immunostimulant plerixafor to the current standard-of-care regimens of granulocyte colony-stimulating growth factor with or without chemotherapy has improved clinical results in terms of successful stem cell mobilization and the outcomes of stem cell transplant in various settings. With this medical innovation has come an added financial cost for institutions where stem cell transplants are routinely performed, and there may be a further financial burden when the contents of partial vials of the drug are wasted, given that plerixafor vials (Mozobil, Sanofi-Aventis Canada Inc) are currently deemed suitable only for single use...

In this study, we showed that G-CSF mobilization increased the frequency of T cells, specifically CD3(+)CD4(+) T cells. G-CSF mobilization decreased the secretion of inflammatory cytokines of CD4(+) T cells through the LFA-1/ICAM-1 signaling pathway, whereas it did not alter the TH1/TH2 ratio. We found that G-CSF mobilization inhibited LFA-1-mediated CD4(+) T cell polarization and motility. In vitro, G-CSF stimulation also attenuated the polarization and adhesiveness of CD4(+) T cells through the LFA-1/ICAM-1 interaction...
