  1. 16. Auxiliary Cells for the Vascularization and Function of Endogenous and Transplanted Islets of Langerhans

    Författare :Liza Grapensparr; Per-Ola Carlsson; Leif Jansson; Mia Phillipson; Aileen King; Uppsala universitet; []
    Nyckelord :Islets of Langerhans; beta cells; diabetes; transplantation; vascularization; Schwann cells; endothelial progenitor cells; neural crest stem cells; Medicinsk vetenskap; Medical Science;

    Sammanfattning : Type 1 diabetes develops through the progressive destruction of the insulin-producing beta-cells. Regeneration or replacement of beta-cells is therefore needed to restore normal glucose homeostasis. Presently, normoglycemia can be achieved by the transplantation of whole pancreas or isolated islets of Langerhans. LÄS MER

  2. 17. Functional studies of two forkhead genes

    Författare :Mikael Heglind; Göteborgs universitet; []
    Nyckelord :forkhead genes; Foxs1; Foxi1; vacuolar type H -ATPase; boundary cap; neural crest stem cells;

    Sammanfattning : Forkhead genes are functionally diverse and several have been linked to human disease. A previous screen for forkhead genes identified the family member FOXS1. To characterize the function of this gene, we produced a mouse model in which the Foxs1 gene was replaced by a lacZ marker allele. LÄS MER

  3. 18. Neuroprotection in the Injured Spinal Cord : Novel Strategies using Immunomodulation, Stem cell Transplantation and Hyaluronic acid Hydrogel carriers

    Författare :Nikos Schizas; Nils Hailer; Elena Kozlova; Mikael Svensson; Uppsala universitet; []
    Nyckelord :Hyaluronic Acid-based hydrogel; motorneurons; microglial cells; Interleukin-1 Receptor Antagonist; Renshaw cells; excitotoxicity; neuroinflammation; Neural Crest Stem Cells; Medicinsk vetenskap; Medical Science;

    Sammanfattning : The overall aim of this thesis was to establish strategies to minimize secondary damage to the injured spinal cord. Secondary damage that follows spinal cord injury (SCI) involves inflammatory and excitotoxic pathways. LÄS MER

  4. 19. Optimization and validation of a species-specific in vivo approach for studies on growth and progression of neural crest derived tumours

    Författare :Jessica Cedervall; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Background: Despite great advantages in cancer therapeutics during the last decades, therapy-resistance remains a problem in the majority of malignancies. Hence, development of more effective therapeutics is critical to enhance survival of patients with cancer. LÄS MER

  5. 20. Early function of KCC2 and Wnt genes : cytoskeletal effects in neural stem cells

    Författare :Zachi Horn; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : From closure of the neural tube until formation of neuronal networks, cells undergo several crucial changes which depend on the expression of many important molecules. GABA, the principal inhibitory neurotransmitter in the adult nervous system, acts as an excitatory signal during embryonic development. LÄS MER
