  1. 1. Airway epithelial shedding: Morphological and functional aspects in vivo

    Författare :Jonas Erjefält; Luftvägsinflammation; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; eosinophils; neutrophils; plasma exudation; barrier restitution; basal cells; ciliated cells; secretory cells; Epithelial repair; epithelial shedding; fibrinogen; fibronectin; Respiratory system; Andningsorganen;

    Sammanfattning : Epithelial damage may contribute to the pathology in airway diseases such as asthma and rhinitis. However, the distribution of epithelial shedding in inflammatory airway diseases and, particularly, the ensuing repair processes are largely unknown. LÄS MER

  3. 2. The role of progesterone in the regulation of ciliary activity in the fallopian tube

    Författare :Magdalena Nutu; Göteborgs universitet; []
    Nyckelord :progesterone; progesterone receptor; non-genomic progesterone receptor; ciliated cells; fallopian tube; gamete transport; ciliary activity; ciliary beat frequency; reproduction; fertility;

    Sammanfattning : The overall aim of this thesis was to investigate the distribution and regulation of membrane progesterone receptors (mPRs) that may be involved in regulating ciliary activity in the fallopian tube. The fallopian tube serves to transport the egg and spermatozoa to achieve fertilization. LÄS MER

  4. 3. Isolation and characterization of adult neural stem cells

    Författare :Clas B Johansson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Intermediate filaments; GFAP; nestin; scar formation; regeneration; rodent and human neural stem cells; multipotency.;

    Sammanfattning : Injury to the central nervous system (CNS) is one of man's most handicapping situations resulting in severe functional impairment and in some cases a vegetative state where life is supported artificially. The brain and spinal cord, constituting the CNS, have been viewed for decades as having limited capacity of regeneration with no neurogenesis in the adult. LÄS MER

  5. 4. Genetic determinants of epithelial differentiation in the mouse and human lungs

    Författare :Andreas Liontos; Christos Samakovlis; Robert Rottier; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; airway development; single cell; secretory epithelial cells; SCRINSHOT; facultative stem cells; molekylär biovetenskap; Molecular Bioscience;

    Sammanfattning : Several airway epithelial cell types and subpopulations have been defined, using high throughput single-cell mRNA profiling. However, the spectrum and topology of cell populations within the secretory cell lineage has not been explored. LÄS MER

  7. 5. Middle ear structure in relation to function : the rat in middle ear research

    Författare :Nils Albiin; Umeå universitet; []
    Nyckelord :rats; Eustachian tube; ear; middle; tympanic membrane; palatal muscles; mucous membrane; blood vessels; mast cells; otitis media; microscopy; electron;

    Sammanfattning : The present study was undertaken to evaluate the rat as a model for middle ear re­search. The rat was chosen primarily because the gross structure of its middle ear shows several similarities to that of man. LÄS MER
