  1. 1. Specification of Dorsal and Intermediate Telencephalic Character

    Detta är en avhandling från Umeå : Molekylärbiologi (Teknisk-naturvetenskaplig fakultet)

    Författare :Matthew Marklund; [2005]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Molecular biology; telencephalon; forebrain; dorsoventral patterning; WNT; FGF; RA; retinoid-mediated signaling; development; specification; cortex; striatal; intermediate; Molekylärbiologi; NATURAL SCIENCES Biology Cell and molecular biology Molecular biology; NATURVETENSKAP Biologi Cell- och molekylärbiologi Molekylärbiologi; molekylärbiologi; Molecular Biology;

    Sammanfattning : The telencephalon is the most highly evolved region of the vertebrate central nervous system (CNS). The major structures of the telencephalon - the cortex and basal ganglia – derive from the dorsally positioned pallium and the ventrally positioned subpallium, respectively. LÄS MER

  2. 2. Induction of the isthmic organizer and specification of the neural plate border

    Detta är en avhandling från Umeå : Umeå centrum för molekylär medicin (UCMM)

    Författare :Cédric Patthey; Lena Gunhaga; Thomas Edlund; Corinne Houart; [2008]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; neural plate border; neural crest; placodes; Isthmic organizer; Wnt; BMP; FGF; NATURAL SCIENCES Biology Cell and molecular biology; NATURVETENSKAP Biologi Cell- och molekylärbiologi;

    Sammanfattning : The vertebrate nervous system is extremely complex and contains a wide diversity of cell types. The formation of a functional nervous system requires the differential specification of progenitor cells at the right time and place. LÄS MER

  3. 3. Early Rostrocaudal Patterning of the CNS

    Detta är en avhandling från Umeå : Molekylärbiologi (Teknisk-naturvetenskaplig fakultet)

    Författare :Ulrika Nordström; Thomas Edlund; [2005]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; CNS development; neural patterning; neural specification; Wnt; FGF; RA; Isthmic organizer; motor neurons; rostrocaudal patterning.; NATURAL SCIENCES Biology Organism biology Developmental biology; NATURVETENSKAP Biologi Organismbiologi 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

  4. 4. The Role of miRNA in Neurogenesis and Cell Specification

    Detta är en avhandling från Molecular Neurogenetics, Faculty of Medicine, Lund University

    Författare :Malin Åkerblom; [2014]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; miRNA; microRNA; miR-124; miR-9; miR-125; adult neurogenesis; neural stem cells; cell specification; microglia; lentiviral vectors; olfactory bulb; olfactory bulb interneurons;

    Sammanfattning : Only a few decades ago, it was generally believed that gene expression was controlled in a unidirectional way, i.e. DNA was transcribed into RNA, which simply acted as a messenger molecule used to produce the protein that executed cellular functions. LÄS MER

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

    Detta är en avhandling från Malin Parmar, BMC A11, 221 84 LUND

    Författare :Malin Parmar; [2003]
    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
