  1. 1. Studies of neuropeptides in pancreatic beta cell function with special emphasis on islet amyloid polypeptide (IAPP)

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Ella Karlsson; Uppsala universitet.; [2000]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cell biology; alpha cell; amylin; beta cell; chromogranin; growth; IAPP; insulin; islet amyloid polypeptide; leptin; NOD mice; pancreastatin; pancreatic islet; proliferation; Cellbiologi; MEDICINE Morphology; cell biology; pathology Cell biology; MEDICIN Morfologi; cellbiologi; patologi Cellbiologi; medicinsk cellbiologi; Medical Cell Biology;

    Sammanfattning : The presence of protein amyloid in pancreas and its association to diabetes was first described 100 years ago in 1901, but was not identified as Islet Amyloid Polypeptide (IAPP) until 1986. The aim of the present work was to determine the role of the beta cell hormone, IAPP, in normal pancreatic islet physiology and during early disturbances of islet function. LÄS MER

  2. 2. Neogenesis and alloxan toxicity in pancreatic islets, with special reference to the transplanted human β-cell

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Björn Tyrberg; Uppsala universitet.; [1999]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cell biology; Alloxan; β-cell; diabetes; differentiation; growth; insulin secretion; nephrectomy; ob ob; pancreatic islet; transplantation; guinea-pig human; mouse; Cellbiologi; MEDICINE Morphology; cell biology; pathology Cell biology; MEDICIN Morfologi; cellbiologi; patologi Cellbiologi; medicinsk cellbiologi; Medical Cell Biology;

    Sammanfattning : The aim of this work was to study whether adult human pancreatic β-cells have the capacity to proliferate in culture and after transplantation to the renal subcapsular space of mice. An immunosuppressive regimen for human islet discordant xenotransplantation to mice was designed. LÄS MER

  3. 3. Cardiomyocyte Cell Cycle, Renewal and Isolation

    Detta är en avhandling från Cardiovascular Laboratory, Center for Stem Cell Biology, Lund

    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; binucleation; Cardiomyocytes; surface marker; troponin-T; mitosis; microarray; cell cycle; FACS;

    Sammanfattning : Popular Abstract in Swedish Hjärtsjukdom som orsakas av skador på hjärtmuskelceller är en av de vanligaste dödsorsakerna världen över. En framtida önskvärd behandling vore att kunna stimulera kroppens egna förmåga att återskapa hjärtmuskelceller, eller att isolera hjärtmuskelceller framställda i cellkultur. LÄS MER

  4. 4. On the binding of growth-promoting polyamines to proteoglycans: Implications for growth-regulation and polycation-mediated gene transfer

    Detta är en avhandling från Department of Cell and Molecular Biology, Lund University

    Författare :Mattias Belting; Lunds universitet.; Lund University.; [1999]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Genetics; cationic lipid.; gene transfer; gene therapy; cell growth; polyamine transport; spermine; polyamine; growth-inhibition; heparan sulphate; dermatan sulphate; Proteoglycan; glycosaminoglycan; cytogenetics; Genetik; cytogenetik;

    Sammanfattning : Initial investigations were directed at studying the interaction between polyamines and various glycosaminoglycans (GAGs). The polyamine spermine displayed binding to dermatan sulphate (DS) and heparan sulphate (HS) with similar (Kd, 3.9 x 10-4 M) and higher (Kd, 0.37 x 10-6 M) affinity, respectively, than to DNA.

    Sammanfattning : The extracellular matrix is (ECM) is a network of large, structural proteins and polysaccharides, important for cellular behavior, tissue development and maintenance. Present thesis describes work exploring ECM as scaffolds for tissue engineering by manipulating cells cultured in vitro or by influencing ECM expression in vivo. LÄS MER
