Human embryonic stem cells (ESC) are undifferentiated and are endowed with the capacities of self-renewal and pluripotential differentiation. Adult stem cells renew their own tissue, but whether they can transdifferentiate to other tissues is still controversial. To understand the genetic program that underlies the pluripotency of stem cells, we compared(More)
The kinetics of T and B cell immune recovery after bone marrow transplantation (BMT) is affected by many pre- and post-transplant factors. Because of the profoundly depleted baseline T and B cell immunity in recombination activating gene 2 (RAG-2)-deficient severe combined immunodeficiency (SCID) patients, some of these factors are eliminated, and the(More)
BACKGROUND Outcomes of Ewing tumor (ET) patients treated with allogeneic stem cell transplantation (allo-SCT) were compared regarding the use of reduced-intensity conditioning (RIC) and high-intensity conditioning (HIC) regimens as well as human leukocyte antigen (HLA)-matched and HLA-mismatched grafts. PATIENTS AND METHODS We retrospectively analyzed(More)
PURPOSE The ETV6 gene has been reported to be fused to a multitude of partner genes in various hematologic malignancies with 12p13 aberrations. Cytogenetic analysis of six cases of childhood acute lymphoblastic leukemia revealed a novel recurrent t(8;12)(q13;p13), suggesting involvement of ETV6. EXPERIMENTAL DESIGN Fluorescence in situ hybridization was(More)
OBJECTIVE To determine the incidence and clinical consequences of asparaginase-associated lipid abnormalities in children with acute lymphoblastic leukemia (ALL). METHODS Sixty-five newly diagnosed children and adolescents aged 0.4-21 years with ALL or lymphoblastic lymphoma were retrospectively evaluated for lipid abnormalities. They were treated(More)
PURPOSE An encounter between Palestinian parents of children with cancer and Israeli medical staff is a very special situation where "potential enemies" interact in a caring, trusting and intimate relationship for long periods of time. Our aim was to study the psychological and cultural encounter in order to understand the dynamics involved. METHOD The(More)
The safety and efficacy of reduced-intensity conditioning (RIC) regimens for the treatment of pediatric acute myeloid leukemia is unknown. We compared the outcome of allogeneic hematopoietic cell transplantation in children with acute myeloid leukemia using RIC regimens with those receiving myeloablative-conditioning (MAC) regimens. A total of 180 patients(More)
