    Abstract : The extracellular matrix is (ECM) is a network of large, structural proteins and polysaccharides, important for cellular behavior, tissue development and maintenance. Present thesis describes work exploring ECM as scaffolds for tissue engineering by manipulating cells cultured in vitro or by influencing ECM expression in vivo. READ MORE

  4. 2. Label-free processing of stem cell preparations by acoustophoresis

    Author : Franziska Olm; Avdelningen för molekylär hematologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; acoustophoresis; label-free cell separation; ultrasound; microfluidics; stem cell processing; CTC separation;

    Abstract : The first bone marrow transplant in a human was performed in 1959, providing evidence that cells can be used for transplantation and treatment, revealing that healing capacities lie within the human body that ought to be understood. Since then hematopoietic stem cell transplantation has developed as a standard treatment for many cancers besides other malignancies. READ MORE

  5. 3. Measurement of sensitivity to DNA damaging agents

    Author : Sherin T Mathew; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; intrinsic sensitivity; DNA damage; ionizing radiation; cell division;

    Abstract : There is a large inter-individual variation in intrinsic sensitivity in patients receiving treatment with DNA damaging agents. Cancer therapy exemplifies this problem where patients experience varying degree of normal tissue side effects in response to radiation or chemotherapy. READ MORE

  6. 4. Sugar-modulated gene expression and cell division in cell culture and seedlings of A. thaliana

    Author : Sabine Kunz; Leszek A. Kleczkowski; Alison Smith; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Arabidopsis thaliana; carbohydrates; cell culture; cell division; gene expression; homeostasis; live cell imaging; sugar-signals; sugar-analogues; Physiological Botany; fysiologisk botanik;

    Abstract : Throughout their life cycle, plants adjust growth in response to their developmental and environmental situation within the limits of their energetic capacities. This capacity is defined by the local sugar availability, which is constantly modulated through synthesis, transport and consumption of sugar. READ MORE

  7. 5. Neogenesis and alloxan toxicity in pancreatic islets, with special reference to the transplanted human β-cell

    Author : Björn Tyrberg; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cell biology; Alloxan; β-cell; diabetes; differentiation; growth; insulin secretion; nephrectomy; ob ob; pancreatic islet; transplantation; guinea-pig human; mouse; Cellbiologi; Cell biology; Cellbiologi; medicinsk cellbiologi; Medical Cell Biology;

    Abstract : The aim of this work was to study whether adult human pancreatic β-cells have the capacity to proliferate in culture and after transplantation to the renal subcapsular space of mice. An immunosuppressive regimen for human islet discordant xenotransplantation to mice was designed. READ MORE
