In severe acquired aplastic anemia, hematopoietic failure is the result of immune-mediated destruction of bone marrow stem and progenitor cells. Immunosuppressive therapy with antithymocyte globulin (ATG) plus cyclosporine is an effective alternative to stem-cell transplantation and improves blood counts and survival. Although horse ATG is the standard therapy, rabbit ATG is more potent in depleting peripheral-blood lymphocytes and is preferred in other clinical circumstances.

To investigate the effect of 12 weeks of strength training in combination with a nonsteroidal anti-inflammatory drug (NSAID), glucosamine, or placebo on muscle cross-sectional area (CSA), strength (primary outcome parameters), and function, power, pain, and satellite cell number (secondary outcome parameters) in patients with knee osteoarthritis (OA).

to assess the safety and feasibility of combined granulocyte colony-stimulating factor (G-CSF) and erythropoietin (EPO) based intracoronary peripheral blood stem cells (PBSCs) therapy in patients with recent myocardial infarction (RMI) who had successful reperfusion therapy with drug-eluting stent.

The field of autologous stem/progenitor cell therapy for cardiovascular diseases has moved rapidly from bench to bedside. In particular, a small number of pilot studies have demonstrated the safety and efficacy of this treatment in dilated cardiomyopathy (DCM), but this has to be validated in large randomized trials. Here we introduce the Bone Marrow Derived Adult Stem Cells for Dilated Cardiomyopathy (REGENERATE-DCM) trial, which to our knowledge, is the first randomized, double-blind, placebo-controlled trial worldwide to investigate the role of granulocyte-colony stimulating factor and autologous bone marrow-derived stem/progenitor cells to improve cardiac function in patients with DCM.

A growing number of patients with coronary disease have refractory angina. Preclinical and early-phase clinical data suggest that intramyocardial injection of autologous CD34+ cells can improve myocardial perfusion and function.

Atherosclerosis is a progressive disease characterised in part by an imbalance of endothelial decline and endothelial repair. Erythropoietin has been connected to vasculoprotective effects such as enhanced nitric oxide production in endothelial cells and mobilisation of endothelial progenitor cells (EPC).

The p53 antisense oligonucleotide cenersen has been shown to sensitize acute myeloid leukemia (AML) stem cells to DNA damaging agents.

Autologous bone marrow cell transplantation (BMCs-Tx) is a promising novel option for treatment of cardiovascular disease. We analysed in a randomized controlled study the influence of the intracoronary autologous freshly isolated BMCs-Tx on the mobilization of bone marrow-derived circulating progenitor cells (BM-CPCs) in patients with acute myocardial infarction (AMI). Sixty-two patients with AMI were randomized to either freshly isolated BMCs-Tx or to a control group without cell therapy. Peripheral blood (PB) concentrations of CD34/45(+) - and CD133/45(+)-circulating progenitor cells were measured by flow cytometry in 42 AMI patients with cell therapy as well as in 20 AMI patients without cell therapy as a control group on days 1, 3, 5, 7, 8 and 3, 6 as well as 12 months after AMI. Global ejection fraction (EF) and the size of infarct area were determined by left ventriculography. We observed in patients with freshly isolated BMCs-Tx at 3 and 12 months follow up a significant reduction of infarct size and increase of global EF as well as infarct wall movement velocity. The mobilization of CD34/45(+) and CD133/45(+) BM-CPCs significantly increased with a peak on day 7 as compared to baseline after AMI in both groups (CD34/45(+): P < 0.001, CD133/45(+): P < 0.001). Moreover, this significant mobilization of BM-CPCs existed 3, 6 and 12 months after cell therapy compared to day 1 after AMI. In control group, there were no significant differences of CD34/45(+) and CD133/45(+) BM-CPCs mobilization between day 1 and 3, 6 and 12 months after AMI. Intracoronary transplantation of autologous freshly isolated BMCs by use of point of care system in patients with AMI may enhance and prolong the mobilization of CD34/45(+) and CD133/45(+) BM-CPCs in PB and this might increase the regenerative potency after AMI.

The treatment of patients with multiple myeloma usually includes many drugs including thalidomide, lenalidomide and bortezomib. Lovastatin and other inhibitors of HMG-CoA reductase demonstrated to exhibit antineoplasmatic and proapoptotic properties in numerous in vitro studies involving myeloma cell lines. We treated 91 patients with relapsed or refractory multiple myeloma with thalidomide, dexamethasone and lovastatin (TDL group, 49 patients) or thalidomide and dexamethasone (TD group, 42 patients). A clinical response defined of at least 50% reduction of monoclonal band has been observed in 32% of TD patients and 44% of TDL patients. Prolongation of overall survival and progression-free survival in the TDL group as compared with the TD group has been documented. The TDL regimen was safe and well tolerated. The incidence of side effects was comparable in both groups. Plasma cells have been cultured in vitro with thalidomide and lovastatin to assess the impact of both drugs on the apoptosis rate of plasma cells. In vitro experiments revealed that the combination of thalidomide and lovastatin induced higher apoptosis rate than apoptosis induced by each drug alone. Our results suggest that the addition of lovastatin to the TD regimen may improve the response rate in patients with relapsed or refractory myeloma.

Stem cell transplantation is a potential treatment to improve left ventricular ejection fraction (LVEF) after ST elevation myocardial infarction (STEMI). However, the outcomes still are controversial.

Cell therapy is a novel experimental treatment modality for patients with critical limb ischemia (CLI) of the lower extremities and no other established treatment options. This study was conducted to assess the safety and clinical efficacy of intramuscular injection of autologous tissue repair cells (TRCs).

Our objective was to elucidate long-term clinical and functional effects of intramyocardial stem cell transplant and to identify patients who will show sustained benefit.

Peripheral blood stem cell (PBSC) products contain more T cells and monocytes when compared with bone marrow (BM), leading to fewer bacterial and fungal infections. Cytomegelovirus (CMV) viral load and disease as well as CMV-specific immune reconstitution were compared in patients enrolled in a randomized trial comparing PSBC and BM transplantation. There was a higher rate of CMV infection and disease during the first 100 days after transplantation among PBSC recipients (any antigenemia/DNAemia: PBSC, 63% vs BM, 42%, P = .04; CMV disease: PBSC, 17% vs BM, 4%, P = .03). By 2 years, CMV disease rates were similar. The early increase in CMV events correlated temporarily with lower CMV-specific CD4(+) T helper and CD8(+) cytotoxic T lymphocyte function at 30 days after transplantation in PBSC recipients. By 3 months after transplantation and thereafter, CMV-specific immune responses were similar between BM and PBSC recipients. In conclusion, higher CMV infection and disease rates occurred in PBSC transplant recipients early after transplantation. These differences may be because of a transient delay in CMV-specific immune reconstitution following PBSC transplantation.

This study aimed at examining the efficacy of bone marrow mononuclear cell (BMMNC) delivery through graft vessel for patients with a previous myocardial infarction (MI) and chronic heart failure during coronary artery bypass graft (CABG).

Metastatic soft tissue sarcoma (STS) prognosis remains poor and few cytotoxic agents offer proven efficacy. This randomized open phase III study examines whether high-dose (HD) chemotherapy with peripheral blood stem cells (PBSCs) could improve overall survival (OS) of chemosensitive patients.

Autologous bone marrow mononuclear cell (ABMMNC) therapy has shown promise in patients with heart failure (HF). Cell function analysis may be important in interpreting trial results.
