  1. 1. Salivary gland neoplasms : studies on the cytoskeleton, the secretory apparatus and the nuclear DNA content

    Författare :Hans Gustafsson; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Salivary gland neoplasms; intermediate filaments; immuno- histochemistry; ultrastructure; DNA; development; histogenesis; progno¬sis;

    Sammanfattning : The heterogeneity of salivary gland neoplasms have made classification and prognostication of these tumours sometimes difficult, and the in­troduction of techniques, such as enzyme and carbohydrate histochemis­try and electron microscopy have only to a certain extent increased our knowledge in these respects. In the present study immunohistochemical methods have been used to identify intermediate filament proteins (IFP) in normal fetal and adult parotid glands, as well as in salivary neo­plasms. LÄS MER

  5. 4. Human embryonic stem cells for bone engineering applications

    Författare :Giuseppe Maria de Peppo; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Human skeleton; bone; bone defects; bone regeneration; regenerative medicine; tissue engineering; biomaterials; scaffold; biocoral; titanium; osseointegration bioreactor; human stem cells; embryonic stem cells; mesenchymal stem cells; embryonic-derived progenitors; osteogenic differentiation; mineralization; immune response; in vitro; in vivo;

    Sammanfattning : The human skeleton represents the supporting structure of the organism and accounts for about 20 percent of the total body mass. Despite its intrinsic capacity to regenerate and self-repair, this ability is limited and repair therapies are needed in a large number of clinical cases. LÄS MER

  7. 5. Molecular regulation of thyroid development. New mechanisms of normal and defective morphogenesis

    Författare :Henrik Fagman; Göteborgs universitet; []
    Nyckelord :thyroid; congenital hypothyroidism; thyroid dysgenesis; cadherins; pharyngeal arch arteries; Shh; Tbx1;

    Sammanfattning : Congenital hypothyroidism (CH) is untreated a major cause of mental retardation. The majority of cases are due to malformations of the gland (dysgenesis). Little is known of molecular mechanisms regulating thyroid morphogenesis. LÄS MER
