    Författare :Patric Wallin; [2012]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cell migration; lipid bilayers; cell differentiation; liquid handling; surface functionalization; Microfluidics; chemotractant gradients; mammalian cell culture; cell microenvironments; in vitro screening assay;

    Sammanfattning : Stem cells have a great potential to bring about advancements in fields like developmental biology, drug discovery, cancer biology and tissue engineering. In order to be able to use stem cells to their full potential, it is important to have control over their behavior. LÄS MER

  2. 2. Molecular Studies of Mast Cell Migration and Apoptosis Two Ways of Regulating Mast Cell Numbers at Sites of Inflammation

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Jessica Alfredsson; Uppsala universitet.; [2005]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pathology; mast cell; SCF; IL-3; FcεRI; migration; apoptosis; Bim; Bcl-2; Bcl-XL; Akt; FOXO; MAPK; Patologi; MEDICINE Morphology; cell biology; pathology Pathology; MEDICIN Morfologi; cellbiologi; patologi Patologi;

    Sammanfattning : Upon activation mast cells release numerous proinflammatory mediators. With this feature, mast cells play an important role in host defense against pathogens, and are involved in tissue remodeling and wound healing. However, in cases of excessive inflammation the effects of mast cells are detrimental. LÄS MER

  3. 3. Exploring Cellular Dynamics From Vesicle Tethering to Cell Migration

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Parham Ashrafzadeh; Uppsala universitet.; [2016]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; angiogenesis; cancer; cell migration; exocyst complex; exocytosis; FGD5; lipid rafts; plasma membrane; receptor trafficking; VEGFR2;

    Sammanfattning : Cells in the body communicate with each other in order to cooperate efficiently. This communication is in part achieved by regulated secretion of signaling molecules, which when released from a cell may activate receptors present at the plasma membrane of an adjacent cell. Such signals affect both cell fate and behavior. LÄS MER

  4. 4. The role of Smad7 and TRAF6 in Prostate Cancer Cell Invasion, Migration and Survival

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Maria Ekman; Uppsala universitet.; [2011]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TGF-beta; cell migration; invasion; apoptosis; Smad7; APC; ATM; TRAF6; p53; PC3U; Medical Cell Biology; Medicinsk cellbiologi;

    Sammanfattning : Transforming growth factor (TGF) β is a tumor suppressor during early tumor development, by inhibiting proliferation and inducing apoptosis. At later stages of cancer, it becomes a tumor promoter, and promotes tumor cell migration and invasion. TGFβ signals via its type II and type I receptors to several downstream signaling pathways.

  5. 5. Mast Cell Migration in Inflammatory Diseases

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Niclas Olsson; Uppsala universitet.; [2003]
