  1. 6. A genomic approach to smooth muscle differentiation and diversity

    Författare :Sven Nelander; Göteborgs universitet.; Gothenburg University.; [2005]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; 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

  2. 7. Recruitment, Differentiation, and Function of monocytes during Salmonella infection

    Författare :Anna Rydström; Göteborgs universitet.; Gothenburg University.; [2008]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Salmonella; Monocyte; Neutrophil; Chemokine; Toll-like receptor; Differentiation;

    Sammanfattning : Monocytes are a heterogeneous population in the blood with an enormous plasticity whose fate and functions are dictated by the microenvironment. They are phenotypically and functionally related to neutrophils and dendritic cells (DCs) and share an overlapping expression pattern of surface molecules with these cells. LÄS MER

  3. 8. Studies of molecular events during peripheral B cell differentiation

    Detta är en avhandling från Jens Wrammert; BMC I:13; Lund University; 22184 Lund; Sweden

    Författare :Jens Wrammert; Lund University.; Lunds universitet.; [2002]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; transplantation; Immunologi; serologi; serology; Immunology; B cells; Differentiation;

    Sammanfattning : This thesis focuses on molecular changes occuring during terminal B cell differentiation as well as on somatic hypermutation and the generation and maintenance of B cell memory. During T cell dependent immune responses the average affinity for the eliciting antigen increases with time. LÄS MER

  4. 9. Derivation, propagation and differentiation of human stem and progenitor cells

    Detta är en avhandling från Jens Wrammert; BMC I:13; Lund University; 22184 Lund; Sweden

    Författare :Mathilda Zetterström Axell; Göteborgs universitet.; Gothenburg University.; [2009]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Human embryonic stem cells; neural progenitor cells; stem cells; differentiation; propagation; migration; cell culturing; rostral migratory stream; electrospun scaffolds;

    Sammanfattning : Neuronal loss is a common feature of many neurological disorders, including stroke, Parkinson’s disease, Alzheimer’s disease and traumatic brain injury. Human embryonic stem cells (hESCs) and hESC-derived neural progenitors (NPs) may provide a number of new ways for studying and treating diseases and injuries in the brain. LÄS MER

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

    Detta är en avhandling från Umeå : Umeå universitet

    Författare :Lennart Nelson; Umeå universitet.; [1981]
    Nyckelord :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.
