  1. 1. Identification and Characterization of Stem Cells in Preleukemia and Leukemia

    Författare :Lars Nilsson; Stamcellscentrum (SCC); []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Haematology; extracellulära vätskor; Hematologi; Philadelphia chromosome; acute lymphoblastic leukemia; polycytemia vera; 5q- syndrome; myelodysplastic syndromes; self-renewal; preleukemia; Hematopoietic stem cells; leukemic stem cells; extracellular fluids;

    Sammanfattning : Hematopoietic stem cells (HSCs) are responsible for the daily and life long production of large numbers of mature blood cells through highly regulated self-renewal and multilineage capabilities. Leukemias on the other hand, are characterized by a clonal, dysregulated, lineage skewed proliferation and impaired differentiation as the result of multiple accumulated genetic events. LÄS MER

  3. 2. Development of Gene Therapy for Hematopoietic Stem Cells using Lentiviral Vectors

    Författare :Niels-Bjarne Woods; Andreas Ooka; Stefan Karlsson; Avdelningen för molekylärmedicin och genterapi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; embryonic stem cell; Hematopoietic stem cell; lentiviral vector; transduction efficiency; transgene expression; multiple vector copy integration; insertional mutagenesis; NOD SCID mouse; cytogenetics; Genetics; extracellulära vätskor; extracellular fluids; cytogenetik; Genetik; Haematology; Hematologi; Lentivirus : genetics; Human; Genetic Vectors; Hematopoietic Stem Cells : metabolism; Animal; Gene Therapy; Leukemia : therapy; Leukemia : metabolism;

    Sammanfattning : Hematopoietic stem cells are an ideal target for genetic manipulation for the purpose of curing hematological disorders as they have the ability to develop into all blood lineages and to self-renew. In this study we demonstrate that lentiviral vectors, based on HIV-1, can efficiently transfer genes into human hematopoietic progenitor and stem cells as assessed following stem cell transplantation in immune compromised mice.

  4. 3. Targeting residual malignant cells in myeloid leukemia

    Författare :Malin Nilsson; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; acute myeloid leukemia; chronic myeloid leukemia; histamine dihydrochloride; hydroxyurea; leukemic stem cells;

    Sammanfattning : Malignant cells persisting during treatment prevent cure in many patients with myeloid leukemia. In acute myeloid leukemia (AML), the failure to eradicate the leukemic clone during conventional chemotherapy is associated with leukemic relapse, mostly with dismal survival outcome. LÄS MER

  5. 4. Stem and progenitor cell involvement in acute lymphoblastic leukemia

    Författare :Anders Castor; Stamcellscentrum (SCC); []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cancer; Haematology; Cytology; oncology; cancerology; Cytologi; onkologi; Medicin människa och djur ; Medicine human and vertebrates ; ETV6-RUNX1; BCR-ABL1; stem cells; Acute lymphoblastic leukemia; extracellular fluids; Hematologi; extracellulära vätskor;

    Sammanfattning : Leukemic stem cells (LSCs) share the capacity of self renewal and extensive proliferation with normal hematopoietic stem cells (HSCs), and are therefore obvious targets for therapy. As such, they need to be identified and characterized in order to elucidate what drives them, and what separates them from their normal counterparts. LÄS MER

  7. 5. Retroviral gene transfer to repopulating hematopoietic cells

    Författare :Thomas Relander; Tumörmikromiljö; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; GLVR-1; VSV-G; amphotropic; GALV; long-term bone marrow culture; NOD SCID; retroviral vector; hematopoietic stem cells; stem cells; gene transfer; gene therapy; fibronectin; Clinical genetics; Klinisk genetik;

    Sammanfattning : Hematopoietic stem cells (HSCs) have the capacity to maintain hematopoiesis throughout life. HSCs are ideal targets for permanent gene transfer, as the transgene will be expressed in all the progeny of the gene-modified stem cells. LÄS MER
