  1. 1. Migration on extracellular matrix surface and infiltration into matrix - two distinguishable activities of human T cells

    Author : Jyrki Ivanoff; Umeå universitet.; [2003]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Immunology; extracellular matrix; fibronectin; collagen type IV; laminin; neuropeptide; chemokine; TIMP-1; MMP-9; T cells; Migration; Immunologi; MEDICINE Microbiology; immunology; infectious diseases Immunology; MEDICIN Mikrobiologi; immunologi; infektionssjukdomar Immunologi; Clinical Immunology; klinisk immunologi;

    Abstract : Migration of T-lymphocytes on a surface coated with extracellular matrix (ECM) components (two-dimensional (2-D) migration) and migration (infiltration) into a matrix (Three-dimesional (3-D) migration) are complex events and the underlying mechanisms are not yet fully understood. Here 2-D and 3-D migration were studied by use of seven leukemic T-cell lines representing discrete differentiation stages, a non-leukemic T-cell clone, and normal peripheral blood T cells.

  2. 2. Neural Stem Cell Differentiation and Migration

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Anna Erlandsson; Uppsala universitet.; [2003]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicine; CNS; stem cells; neuron; PDGF; SCF; differentiation; migration; ERK; Medicin; MEDICINE Dermatology and venerology; clinical genetics; internal medicine; MEDICIN Dermatologi och venerologi; klinisk genetik; invärtesmedicin; Medical Biochemistry; Medicinsk biokemi;

    Abstract : Neural stem cells are the precursors of neurons, astrocytes and oligodendrocytes. During neural development, the division of stem cells takes place close to the lumen of the neural tube, after which they migrate to their final positions within the central nervous system (CNS).

  3. 3. Studies on extracellular matrix proteins in vascular disease

    University dissertation from Åsa Ström, Section for Connective Tissue Biology, BMC, C12, 221 84 Lund

    Author : Åsa Ström; [2004]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Kardiovaskulära systemet; Cardiovascular system; smooth muscle cells; osteopontin; extracellular matrix; atherosclerosis;

    Abstract : The composition of the vascular extracellular matrix (ECM) is altered during remodeling conditions such as atherosclerosis. The changed ECM regulates events that are important for the progression of disease including smooth muscle cell (SMC) behaviour and collagen fiber formation. READ MORE

  4. 4. Injury-induced activation of vascular smooth muscle cells. Role of specific gene expression and intracellular signalling pathways

    University dissertation from Cecilia Lövdahl, Dept of Cell and Molecular Biology, Section for Connective Tissue Biology, Lund University P.O Box 94, 221 00 Lund, SWEDEN

    Author : Cecilia Lövdahl; [2000]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; metalloproteinase; extracellular matrix; ERK1 2 signalling; migration; proliferation; injury; vessel wall; smooth muscle cell; Medicine human and vertebrates ; Medicin människa och djur ;

    Abstract : Migration and proliferation of smooth muscle cells (SMC) are important events in the development of atherosclerosis and restenosis following angioplastic surgery. It is important to gain further knowledge about the mechanisms regulating SMC form and function in order to understand the underlying disease process. READ MORE

  5. 5. The involvement of gangliosides in growth and migration of human glioblastoma cells

    University dissertation from Cecilia Lövdahl, Dept of Cell and Molecular Biology, Section for Connective Tissue Biology, Lund University P.O Box 94, 221 00 Lund, SWEDEN

    Author : Kristina Hedberg; Göteborgs universitet.; Gothenburg University.; [2001]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Gangliosides synthesis; Ganglioside expression; Glioblastoma; Migration; Proliferation; Cell culture systems; Xenograft model;

    Abstract : Human glioblastoma is a primary brain tumour with a bad prognosis. One major contributing factor is that the tumour grows in an infiltrative way. Single tumour cells, undetectable with today's techniques, invade the brain and escape therapy. READ MORE
