  1. 1. Progenitor cells in the postnatal central nervous system, characterization and genetic manipulation

    Författare :Nina Rogelius; CNS Genterapi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicin människa och djur ; Medicine human and vertebrates ; subventricular zone; Islet1; Neurogenin2; respecification; in vivo.; transcription factors; neurogenesis; Progenitor cells; stem cells;

    Sammanfattning : New neurons are only generated in two places of the postnatal brain; the subventricular zone (SVZ) and hippocampus. The SVZ-derived cells specifically migrate to the olfactory bulb where they give rise to new interneurons. LÄS MER

  2. 2. Stem cell based therapy of malignant brain tumors

    Författare :Daniel Bexell; Sektion IV; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; neural stem cell; pericyte; mesenchymal stem cell; neuroblast; subventricular zone; cancer stem cell; rat; glioma; cancer;

    Sammanfattning : Malignant brain tumor is a highly invasive and vascularized cancer. Current forms of therapy are not curative and can, at best, prolong survival for patients with this disease. The mean survival is only around 15 months. LÄS MER

  3. 3. Neuroprotection and neurogenesis after experimental stroke

    Författare :Andreas Arvidsson; Lund Neurologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; stereology; rat; Neurology; neuropsychology; neurophysiology; Neurologi; neuropsykologi; neurofysiologi; BrdU; immunohistochemistry; in situ hybridization; subventricular zone; striatum; dentate gyrus; neuronal replacement; neuronal survival; Focal cerebral ischemia; glial cell line-derived neurotrophic factor;

    Sammanfattning : In this thesis, two potential endogenous mechanisms for neuronal survival and repair have been investigated in a rat model of stroke, middle cerebral artery occlusion (MCAO): signaling of the GDNF family of neurotrophic factors, and neurogenesis from endogenous progenitor cells. As determined by in situ hybridization for GDNF family ligand and receptor genes, MCAO caused widespread upregulation of both components of the functional GDNF receptor, c-Ret and GFRalpha1, indicating that GDNF may be a survival signal in stroke.

  4. 4. Neural Progenitor Cells in malignancy and injury of the brain. A Trojan Horse fro gliomas?

    Författare :Karin Staflin; CNS Genterapi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; serologi; transplantation; Immunologi; Medicine human and vertebrates ; Medicin människa och djur ; Immunology; serology; Glioma; sub ventricular zone; neural progenitor cell;

    Sammanfattning : Gliomas are neoplasms arising in the central nervous system (CNS), and constitute the most common primary brain tumor. They are classified depending on the grade and morphology, from grade I, pilocytic astrocytoma, to grade IV, glioblastoma multiforme (GBM). Glioblastomas constitute a great challenge in treatment due to their disseminating nature. LÄS MER

  5. 5. Adult human neural stem cells : properties in vitro and as xenografts in the spinal cord

    Författare :Ulf Westerlund; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Action potential; adult; allodynia; auto-transplantation; endoscope; glutamate; hippocampus; human; neural stem cells; p75; patch clamp; progenitor; spinal cord injury; subventricular zone; synapse; transplantation;

    Sammanfattning : Though the presence of stem cells in the adult human brain has been presented earlier, much has yet to be discovered about these cells. However, the mere potential of these cells has had a significant impact of how we today evaluate the regenerative capacity of the central nervous system and, importantly, on the possible means for science to provide insights in neural repair.
