  1. 1. Early Rostrocaudal Patterning of the CNS

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

    Sammanfattning : 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. LÄS MER

  2. 2. Early development of the olfactory placode and early rostrocaudal patterning of the caudal neural tube

    Författare :Esther Maier; Lena Gunhaga; Fernando Giraldez; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; olfactory placode; caudal neural tube; Wnt; FGF; RA; BMP; Notch; patterning; Developmental biology; Utvecklingsbiologi; molekylärbiologi; Molecular Biology;

    Sammanfattning : The development of the nervous system is a complex process. Cell divisions, cell differentiation and signalling interactions must be tightly regulated. To comprehend the mature nervous system, we have to understand its assembly during development. LÄS MER

  3. 3. Regulation of morphogen signalling during neural patterning in the Xenopus embryo

    Författare :Hooi Min Tan Grahn; Avdelningen för molekylärmedicin och genterapi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Suppressor-of-fused; Gli; β-Catenin; Neural; Xenopus; FGF; Signalling; HtrA1; RDH10; Retinol dehydrogenase; Retinoic acid; Spemann s organizer; Induction; Gradient;

    Sammanfattning : Morphogens such as Hedghog, Wnt, FGF, and retinoic acid are important signals whose concentrations need to be tightly regulated in the vertebrate embryo to ensure body axis development and formation of the central nervous system. We first show that the intracellular cytoplasmic protein XSufu acts as a dual regulator of Hedgehog (Hh) and Wnt signals during neural induction and patterning in the Xenopus embryo. LÄS MER

  4. 4. Integration of Electrospun Materials in Microelectronic and Biomedical Applications

    Författare :Björn Carlberg; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; microstructure; electrospinning; interpenetrating phase; stem cell; photolithography; patterning; thermal management; thermal interface material; scaffold;

    Sammanfattning : This thesis demonstrates the use of electrospinning and the novel properties of electrospunmaterials in two fields.The microelectronics industry has identified thermal interface materials as one of themajor bottlenecks hindering further integration at packaging level. LÄS MER

  5. 5. Adult neural stem cells in neuroinflammation

    Författare :Ruxandra Covacu; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Neural stem cells; inflammation; EAE; NO; neurogenesis; HMGB1; TLR; TNFalpha;

    Sammanfattning : Adult neural stem cells (NSC) can be isolated from the subventricular zone (SVZ) of the lateral ventricles, the subgranular zone (SGZ) of the hippocampus and the central canal of the spinal cord. These cells are thought to have regenerative potential and pose important therapeutic possibilities in neuroinflammatory conditions such as Multiple Sclerosis (MS). LÄS MER
