Central issues in intracoronary infusion (ICI) of bone marrow (BM)-cells to damaged myocardium for improving cardiac function are the cell number that is feasible and safe to be administrated as well as the retention of cells in the target area. Our study addressed these issues in eight patients with chronic ischemic cardiomyopathy undergoing ICI of(More)
OBJECTIVES The long-term effect of intracoronary infusion of progenitor cells in patients with chronic ischemic cardiomyopathy. BACKGROUND Bone marrow stem-cell administration in patients with myocardial infarction improved myocardial performance and in some studies contributed to favorable left ventricular remodeling. METHODS We report on the results(More)
Endothelial progenitor cells (EPCs) and the recently described circulating fibrocytes (CFs) are strongly associated with tissue repair. We investigated the kinetics of both "repair" progenitor cells in healthy athletes who participated in the "Spartahlon" ultradistance foot race (246 km continuous running exercise), which provides a unique model of inducing(More)
Various polymorphisms in cytokine genes have recently been investigated as candidate risk factors in allogeneic hematopoetic stem cell transplantation (allo-HSCT). We retrospectively analyzed specific polymorphisms in genes for interleukin (IL)-10, IL-6, tumor-necrosis factor alpha (TNF-α) and interferon gamma (IFN-γ) in a pediatric cohort of 57(More)
To address how low titer, variable expression, and gene silencing affect gene therapy vectors for hemoglobinopathies, in a previous study we successfully used the HPFH (hereditary persistence of fetal hemoglobin)-2 enhancer in a series of oncoretroviral vectors. On the basis of these data, we generated a novel insulated self-inactivating (SIN) lentiviral(More)
The 5-transmembrane receptor AC133 is expressed on a subpopulation of human hematopoietic cells that includes the CD34(bright) cells. We evaluated the developmental potential of AC133+CD34(bright) and AC133(dim/-)CD34+ cells isolated from 5 cord blood (CB) samples by studying the in vitro proliferative and differentiative potential of each population in(More)
Directed sibling cord blood banking is indicated in women delivering healthy babies who already have a sibling with a disease that is potentially treatable with an allogeneic cord blood transplant. We evaluated the effectiveness of a national directed cord blood banking program in sibling HLA-identical stem cell transplantation for hematological(More)
Several cord blood banks store cord blood units from healthy siblings of patients, who are candidates for stem cell transplantation. We analyzed the quality characteristics of 50 cord blood units collected from families with beta-thalassemia major and the outcome of subsequent stem cell transplantations during a 15-year period. All cord blood units were(More)
BU combined with CY, the preferred preparatory regimen for thalassemic patients, is associated with a substantial incidence of graft rejection especially in patients with advanced disease stage. This study retrospectively analyzes the outcome of 75 consecutive pediatric patients with β-thalassemia who underwent HLA-matched sibling transplantation after(More)
