  1. 1. Tissue specific functions of Early B-cell factor in cellular differentiation

    Författare :Anna Lagergren; Stamcellscentrum (SCC); []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; transcription factor; extracellular fluids; Haematology; tissue specific; cellular differentiation; EBF; Hematologi; extracellulära vätskor;

    Sammanfattning : This work focus on the functions by which the transcription factor Early B-cell Factor (EBF) regulate gene expression in different cell types. To address this question, gene expression analyses aimed to investigate the regulatory role of EBF in neuroblastoma cells, B-lymphocytes, adipocytes and stromal cells were performed. LÄS MER

  2. 2. Neural Stem and Progenitor Cells : Cellular Responses to Known and Novel Factors

    Författare :Jimmy Larsson; Karin Forsberg-Nilsson; Ola Hermanson; Uppsala universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; neural stem cell; differentiation; proliferation; migration; PDGF; SCF; NRBP2; medulloblastoma; Biochemistry; Biokemi; Medical Biochemistry; Medicinsk biokemi;

    Sammanfattning : Neural stem cell self-renewal and differentiation are tightly regulated events during CNS development, leading to cell division into new neural stem cells or the formation of neurons and glial cells. This thesis focuses on the cellular responses induced by known and novel factors in neural stem and progenitor cells (NSPCs). LÄS MER

  3. 3. Device Bonding and Antibody Binding: Developments for On-Chip Differentiation of Induced Pluripotent Stem Cells into Hepatocytes

    Författare :Philip Dalsbecker; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Nyckelord :NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; NATURAL SCIENCES; Microfluidics; liver-on-a-chip; organ-on-chip; PDMS; oxygen plasma; immunofluorescence; fluorescence microscopy; hepatocytes; iPSC; induced pluripotent stem cells; differentiation; on-chip differentiation; definitive endoderm;

    Sammanfattning : Abstract This thesis describes the bonding optimization of a liver-on-a-chip microfluidic device for evaluation of cultured induced pluripotent stem cell (iPSC)-derived definitive endoderm (DE) cells during their targeted differentiation into mature hepatocytes. Furthermore, it describes the optimization of a number of antibody assays for use during said differentiation, for the purpose of studying the cellular phenotype. LÄS MER

  4. 4. A genomic approach to smooth muscle differentiation and diversity

    Författare :Sven Nelander; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Nyckelord :Keywords: smooth muscle; phenotype; transcriptional regulation; differentiation; transcriptome; microarray; computational prediction; co-expression network; regulatory sequence analysis; gene module; gene battery;

    Sammanfattning : Smooth muscle cells (SMCs) are a broad class of contractile cells that are found in a number of organs systems, including the vasculature, the urogenital system, the bronchi and the gastrointestinal tract. The two main functions exerted by SMCs are to provide contractile force and to synthesize structural components of the extracellular matrix. LÄS MER

  5. 5. Mitochondrial differentiation during the early development of the amphibian embryo

    Författare :Lennart Nelson; Barbara Cannon; Umeå universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Amphibia; Xenopus laevis; Ambystoma mexicanum; mitochondria; differentiation; enzymes; carriers; oxidation; development; Zoophysiology; zoofysiologi;

    Sammanfattning : Mitochondria from Xenopus laevis and Ambystoma mexica- num embryos between fertilization and the beginning of feeding were studied: the former with respect to metabolic behaviour, enzyme pattern and carrier activity, and the latter with respect to morphological parameters.The metabolic behaviour of mitochondria was studied by assessing the rates of oxygen uptake in presence of various substrates.
