1. 21. 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. 22. Live and Let Die : Critical regulation of survival in normal and malignant hematopoietic stem and progenitor cells

   Författare :Pernilla Eliasson; Jan-Ingvar Jönsson; Mikael Sigvardsson; Urban Gullberg; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; hematopoietic stem cells; hypoxia; self-renewal; survival; acute myeloid leukemia; FLT3; Cell and molecular biology; Cell- och molekylärbiologi; Haematology; Hematologi;

   Sammanfattning : The hematopoietic stem cell (HSC) is characterized by its ability to self-renew and produce all mature blood cells throughout the life of an organism. This is tightly regulated to maintain a balance between survival, proliferation, and differentiation. LÄS MER

4. 23. Restoring antitumor immunity with dendritic cell reprogramming strategies. Reprogramming cancer cells to antigen-presenting cells

   Författare :Alexandra Gabriela Barros Ferreira; Avdelningen för molekylärmedicin och genterapi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cell Reprogramming; Cancer cells; Tumor Antigen-presenting Cells; immunotherapy;

   Sammanfattning : For the past two decades, immunotherapy revolutionized cancer treatment. However, responses vary significantly among eligible patients and some cancer types are not yet open to immunotherapy. Several mechanisms contribute to immunotherapy resistance, including loss of antigen presentation machinery and immunosuppression. LÄS MER

5. 24. Smad signaling in hematopoietic stem cell biology

   Författare :Göran Karlsson; Avdelningen för molekylärmedicin och genterapi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Smad7; Smad4; microarray; retroviral-mediated gene expression; conditional knockout; transforming growth factor beta; smad signaling; hematopoiesis; hematopoietic stem cells; Alk5; Medicine human and vertebrates ; Medicin människa och djur ;

   Sammanfattning : Hematopoietic stem cells (HSCs) are primitive tissue-specific somatic stem cells, responsible for the maintenance and replenishment of the bone marrow (BM) and subsequently the entire blood system. The never-ending ability to differentiate into all the mature hematopoietic lineages makes these HSCs attractive candidates for use in future regenerative medicine. LÄS MER

7. 25. Maintenance and Commitment of Hematopoietic Progenitors: Role of flt3, c-kit and c-mpl

   Författare :Ole Johan Borge; Avdelningen för molekylärmedicin och genterapi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; KL; hematopoiesis; FL; cytokines; B-cells; commitment; flt3; differentiation; Haematology; IL-7; c-kit; progenitors; Hematologi; stem cells; thrombopoietin; viability; extracellular fluids; extracellulära vätskor;

   Sammanfattning : The need for red blood cells to transport oxygen and CO2, blood platelets to stop bleedings, and neutrophils, macrophages, B- and T-cells for host defense, is a prerequisite for life. These mature blood cells have a limited life span and are thus constantly replenished by an enormous cell production (estimated to 1012 cells per day) which primarily takes place in the bone marrow (BM).
