  1. 1. Rho-GTPases in Morphogenesis and Differentiation of the Developing Pancreas

    Detta är en avhandling från Lund University

    Författare :Thomas Greiner; Lunds universitet.; Lund University.; [2009]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; insulin; diabetes; beta cell; cell adhesion; migration; delamination; morphogenesis; tubulogenesis; pancreas; Cdc42; Rho-GTPase; Rac1;

    Sammanfattning : Branched tubular networks constitute the basic structure of many organs to increase surface area and to transport fluids and gases. Glandular organs such as the pancreas arise from multilayered epithelium, which undergoes de novo lumen formation and extensive remodeling and branching. LÄS MER

  2. 2. From Cell Shape to Body Shape: Epithelial Morphogenesis in Drosophila melanogaster

    Detta är en avhandling från Department of Experimental Medical Science, Lund Univeristy

    Författare :Shai Mulinari; Lunds universitet.; Lund University.; [2008]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Odd-skipped; morphogenesis; Hedgehog; segment boundaries; segmental grooves; Actin; Drosophila; DRhoGEF2; Myosin; Diaphanous; Rho GTPase; cytoskeleton; Rho1;

    Sammanfattning : Embryonic development is associated with extensive rearrangements of tissues. The driving force for these rearrangements is generated by a dynamic reorganization of the Actin cytoskeleton of individual cells. LÄS MER

  3. 3. Basement membrane components and their receptors in organogenesis

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Katriina Salmivirta; Uppsala universitet.; [1999]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Developmental biology; Basement membrane; laminin; collagen type IV; nidogen; integrin; morphogenesis; organogenesis; tooth; salivary gland; Utvecklingsbiologi; NATURAL SCIENCES Biology Organism biology Developmental biology; NATURVETENSKAP Biologi Organismbiologi Utvecklingsbiologi; fysiologi; Physiology;

    Sammanfattning : During embryogenesis organs are formed from epithelial and mesenchymal tissues. Organogenesis is dependent on interactions between epithelium and mesenchyme. Specialized extracellular matrices, basement membranes, located between the two tissue types play a crucial role in mediating the interactions. LÄS MER

  4. 4. Imaging the pancreas new aspects on lobular development and adult constitution

    Detta är en avhandling från Umeå : Umeå universitet

    Författare :Andreas Hörnblad; Umeå universitet.; [2011]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Type 1 diabetes; ß-cell mass; tertiary lymphoid organs; biomedical imaging; optical projection tomography; morphogenesis; pancreas development; gastric lobe; spleen development.; medicinsk genetik; Medical Genetics; medicinsk utvecklings- och neurobiologi; Developmental Neurosciences; molekylär medicin genetik och patologi ; Molecular Medicine;

    Sammanfattning : The mouse pancreas is a mixed exocrine and endocrine glandconsisting of three lobular compartments: the splenic, duodenal and gastric lobes. During embryogenesis, the pancreas forms from two progenitor populations located on the dorsal and ventral side of the primitive gut tube. LÄS MER

  5. 5. Molecular regulation of epithelial tube size

    Detta är en avhandling från Umeå : Umeå universitet

    Författare :Erika Tång Hallbäck; Göteborgs universitet.; Gothenburg University.; [2009]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Drosophila; tube shape; trachea; chitin; luminal matrix; epithelial tubes; morphogenesis; chloride channel; subapical actin;

    Sammanfattning : In nature, epithelial tubes are vital structures in organ design and are required for transport of gases and liquids in organs, such as the vascular system, the vertebrate lung and the kidneys. The tubular epithelium is single layered, but is often reinforced by layers of muscular support. LÄS MER
