  1. 1. Hematopoiesis in a Crustacean

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Abstract : Hemocytes (blood cells) play an important role in the immune response in invertebrates, and thus the regulation of hemocyte homeostasis (hematopoiesis) is essential for the host survival against pathogens. Astakine 1, a homologue to vertebrate prokineticins, was first identified in the freshwater crayfish Pacifastacus leniusculus as a cytokine, and was found to be necessary for new hemocyte synthesis and release in vivo, and also to induce spreading and proliferation of Hematopoietic tissue cells (Hpt cells, precursor of hemocytes) in vitro.

  2. 2. The Role of HoxB4 in Hematopoiesis

    University dissertation from Ann Brun, Molecular Medicine and Gene Therapy, BMC A12, 221 84 Lund, Sweden

    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Hematologi; extracellulära vätskor; Haematology; extracellular fluids; adenovirus; gene transfer; knock out; HOXB4; HOXB3; homeobox genes; hematopoietic stem cells; Transcription factors; hematopoiesis;

    Abstract : Popular Abstract in Swedish I kroppen produceras varje dag ca 1 000 000 000 000 nya blodceller för att ersätta celler som förbrukats eller sorterats undan som odugliga. I toppen av hierarkin finns den hematopoietiska stamcellen, eller blodstamcellen, en cell med ett antal unika egenskaper: (i) Förmågan att dela sig och ge upphov till minst en ny blodstamcell (cell med samma egenskaper som modercellen) (ii) Förmågan att kunna mogna ut till alla typer av celler som behövs i blodet (iii) Förmågan att vid transplantation till en annan individ kunna tillverka ett helt nytt blodsystem från en enda cell.

  3. 3. The role of TGF-§ in hematopoiesis

    University dissertation from Jonas Larsson, BMC A12, 221 84 Lund

    Author : Jonas Larsson; Lunds universitet.; Lund University.; [2002]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Transforming growth factor-§; Cre loxP system; receptor; knockout; embryogenesis; angiogenesis; hematopoiesis; hematopoietic stem cell; inflammation; Medicine human and vertebrates ; Medicin människa och djur ;

    Abstract : Transforming growth factor-§ (TGF-§) is a potent, multifunctional growth factor affecting virtually all cell types, regulating critical physiological processes like immune response, wound healing, angiogenesis, and tumor development. A large number of studies in vitro have also implicated a critical role of TGF-§ in regulating hematopoiesis by inhibiting proliferation of hematopoietic stem cells (HSCs). READ MORE

  4. 4. The Biology of Hematopoietic Stem Cells: transgenic approaches to Dissect Native and Perturbed Hematopoiesis

    University dissertation from Lund University, Faculty of Medicine

    Author : Petter Säwén; Lunds universitet.; Lund University.; Lunds universitet.; Lund University.; [2017-10-06]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Hematopoiesis is defined as the ongoing production of blood cells. As most mature blood cells are relatively short-lived and require continuous replacement, hematopoiesis is characterized by an extraordinary turnover rate with production of trillions of new blood cells every day.

  5. 5. The Role of Hepatic Leukemia Factor in Hematopoiesis

    University dissertation from Lund University, Faculty of Medicine

    Author : Karolina Komorowska; Lunds universitet.; Lund University.; [2018]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Hematopoiesis; Hematopoietic Stem Cells; knockout mice; HLF; Transcription Factor; aging;

    Abstract : The development of therapeutic methods based on stem cells (e.g. cell therapy, activating regeneration and organ transplantation), known as regenerative medicine, is still a novel area in the field of life sciences. READ MORE
