  1. 16. Manipulating neural stem cells

    Författare :Malin Eriksson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The stem cell field is a fairly young but fast growing scientific field. Our understanding of stem cells has changed tremendously over the last couple of decades. This in mainly due to the development of new techniques that has enabled us to study stem cells from a completely new perspective. LÄS MER

  3. 17. Molecular specification of expanded forebrain neural stem and progenitor cells

    Författare :Malin Parmar; Neurobiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; teratology; ontogeny; embryology human ; Development biology; developmental control genes; in vitro expansion; transplantation; precursor cell; stem cells; progenitor cell; human; mouse; Utvecklingsbiologi; teratologi; embryologi människa ;

    Sammanfattning : The molecular specification of neural precursor cells has been suggested to be a progressive process, with a transition from an early requirement for extrinsic signals to intrinsic mechanisms. Thus, the cells in the nervous system acquire distinct fates in response to extrinsic signals, which activate repertoires of transcription factors in a region and cell type specific manner. LÄS MER

  4. 18. Hormonal Regulation of Neural Stem Cell Proliferation and Fate Determination

    Författare :Karin Brännvall; Dan Lindholm; Sandra Ceccatelli; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurosciences; Neural stem cell; Proliferation; Fate determination; Hormones; Anabolic androgenic steroids; Neurovetenskap; Neurology; Neurologi;

    Sammanfattning : Stem cells have the capacity for both self renewal, and to form all cell types in the body. Interestingly, so called neural stem cells (NSCs) are found in the adult human brain, which is of significance both out of a developmental perspective and from a clinical point of view. LÄS MER

  5. 19. Stem Cell Transplantation in Dorsal Root Injury

    Författare :Carl Trolle; Elena Kozlova; Niklas Marklund; Karin Nordström; Michael Andäng; Mårten Risling; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Sensory Neuron; Regeneration; Spinal Root; Stem Cell; Neuroscience; Neurovetenskap;

    Sammanfattning : After traumatic injuries to the brachial plexus there is a risk that one or more of the spinal roots are torn from the spinal cord, known as avulsion injury. This often leads to paralysis and chronic pain, notoriously difficult to treat with current pharmacotherapy. LÄS MER

  7. 20. Visualization and manipulation of microRNA in neural cells

    Författare :Rohit Sachdeva; Molekylär neurogenetik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; microRNA; miRNA; miR-124; miR-9; embryonic stem cells; neural stem cell; cell transplantation; neurogenesis; microglia;

    Sammanfattning : microRNA (miRNA) are small non-coding RNA, 21-23 nucleotides long. miRNA provide a new layer of regulatory control over gene expression programs. It is increasingly evident that miRNA are cell type and tissue specific. Many miRNAs have been identified to be highly abundant in certain regions of the brain. LÄS MER
