  2. 1. Interactions between mouse CNS cells : microglia and neural precursor cells

    Author : Johan Aarum; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Aggregate cultures; cell markers; CNS; differentiation; fetal; immunohistochemistry; microglia; migration; neural stem cells; phage display; precursor; Slit.;

    Abstract : The mammalian central nervous system (CNS) contains a variety of cells, all specialized to perform different functions. Most numerous are the three types of glia cells, whose basic role is to support the signaling units of the CNS, the neurons. READ MORE

  4. 2. Assessment of precursor cell proliferation in normal and injured adult mammalian brains

    Author : Hong Zhu; Göteborgs universitet; []
    Keywords : 6-OHDA; astrocytes; cell proliferation; neural stem cells; ; neurogenesis; precursor cells; seizure; SVZ-OB pathway;

    Abstract : In the adult mammalian brain, new neurons are generated from neural stem cells (NSCs) which reside in the subventricular zone (SVZ) of the lateral ventricle wall and in the subgranular zone (SGZ) of the dentate gyrus (DG) in the hippocampus. The biology of persistent NSCs in the adult brain is poorly understood. READ MORE

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

    Author : Malin Parmar; Neurobiologi; []
    Keywords : 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 ;

    Abstract : 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.

  6. 4. Human neural precursor cells in spinal cord repair

    Author : Junghua Piao; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Traumatic spinal cord injury (SCI) often results in substantial neural cell death, axonal degeneration and demyelination, accompanied by loss of sensory and motor functions. Cell therapy may have neuroprotective effects, substitute for lost neural cells, promote regeneration and enhance remyelination in the lesioned spinal cord. READ MORE

  7. 5. Early Rostrocaudal Patterning of the CNS

    Author : Ulrika Nordström; Thomas Edlund; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; CNS development; neural patterning; neural specification; Wnt; FGF; RA; Isthmic organizer; motor neurons; rostrocaudal patterning.; Developmental biology; Utvecklingsbiologi;

    Abstract : The transformation of an initially uniform population of epiblast cells into an intricately complex central nervous system (CNS) is one of the most fascinating processes during embryonic development. Presumptive neural cells are initially specified as cells of forebrain character. READ MORE
