2. 6. Molecular and cellular analysis of Lhx2 function in hematopoietic stem cells

   Author : Karin Richter; Leif Carlsson; Andrew Elefanty; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Hematopoietic stem cells; Lhx2; cell lines; self renewal; SCF; IL-6; chronic myeloproliferative disorder; global gene expression analysis; Molecular biology; Molekylärbiologi;

   Abstract : The formation of blood, hematopoiesis, is a dynamic process originating from a small number of hematopoietic stem cells (HSCs). To sustain hematopoiesis throughout life HSCs have the unique capacity to differentiate into all mature hematopoietic lineages as well as generating more HSCs by a mechanism referred to as self-renewal.

4. 7. Identification and Characterization of Stem Cells in Preleukemia and Leukemia

   Author : Lars Nilsson; Stamcellscentrum (SCC); []
   Keywords : 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;

   Abstract : 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. READ MORE

5. 8. Smad signaling in hematopoietic stem cell biology

   Author : Göran Karlsson; Avdelningen för molekylärmedicin och genterapi; []
   Keywords : 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 ;

   Abstract : 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. READ MORE

6. 9. Studies on arachidonic acid metabolism in normal and malignant hematopoietic cells

   Author : Stina Feltenmark; Karolinska Institutet; Karolinska Institutet; []
   Keywords : ;

   Abstract : This thesis deals with the metabolism of arachidonic acid via the 5-lipoxygenase- and the 15-lipoxygenase-1 pathways in normal and malignant hematopoietic cells. The first part of the thesis (papers I & II) describes the expression of genes involved in arachidonic acid metabolism and the capacity to generate leukotriene (LT) B4 via the 5-lipoxygenase pathway in blood tumor cells from patients with precursor B-ALL (acute lymphoblastic leukemia) and AML (acute myeloid leukemia).

7. 10. Targeting the hematopoietic stem cell to correct osteopetrosis

   Author : Carmen Flores Bjurström; Avdelningen för molekylärmedicin och genterapi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Hematopoietic stem cells; bone marrow transplantation; gene therapy; osteoclasts; infantile malignant osteopetrosis;

   Abstract : This thesis focuses on developing stem cell targeted gene therapy for the severe hereditary disorder Infantile Malignant Osteopetrosis (IMO) as well as increasing the understanding of how the genetic defect present in IMO affects the hematopoietic stem cells and hematopoiesis in general. IMO is a rare congenital disorder associated with an increased number of non-functional osteoclasts and the absence of bone resorption results in accumulation of sclerotic bone leading to abnormal bone marrow cavity formation insufficient to support hematopoiesis.
