  2. 16. Stem cells in the adult heart - 3D culture, isolation of side population cells and search for a stem cell niche

    Author : Kristina Vukusic; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Heart; cardiac stem cells; Stem cell niche; Atrioventricular junction; Side population; 3D culture;

    Abstract : Cardiac tissue shows a poor regenerative capacity. From 2003 reports, mostly based on animal models, have showed existence of stem cells also in the heart. Using 14C measurements, a slow but steady turnover of the cardiac cells was shown in humans, around 1%/year. As a source for this regeneration endogenous stem cells have been suggested. READ MORE

  4. 17. The release of histone proteins from cells via extracellular vesicles

    Author : Uma Muthukrishnan; Jonathan Gilthorpe; Miles Trupp; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Histone; extracellular vesicles; exosomes; extracellular histones extracellular DNA; cellular stress; proteomics; ESCRT complex; Lrrn1; mid-hindbrain organizer; ovarian cancer; ascites;

    Abstract : Histones are chromatin-associated proteins localized to the nucleus. However, extracellular histones are present in biofluids from healthy individuals and become elevated under disease conditions, such as neurodegeneration and cancer. READ MORE

  5. 18. Cardiomyocyte Cell Cycle, Renewal and Isolation

    Author : Stuart Walsh; Stamcellscentrum (SCC); []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; binucleation; Cardiomyocytes; surface marker; troponin-T; mitosis; microarray; cell cycle; FACS;

    Abstract : Heart disease results from the loss of cardiomyocytes following myocardial damage and is a leading cause of death worldwide. Stimulating the endogenous regeneration of cardiomyocytes or isolating them from in vitro culture is an attractive therapeutic strategy. READ MORE

  6. 19. Glucose- and hypoxia-regulated insulin gene expression

    Author : Linda Tillmar; Jens Höiriis Nielsen; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cell biology; islet; beta-cell; insulin; mRNA stability; PTB; glucose; hypoxia; mTOR; p70s6k; ceramide; redox; ROS; Cellbiologi; Cell biology; Cellbiologi; medicinsk cellbiologi; Medical Cell Biology;

    Abstract : Although extensively studied, there are still many unanswered questions regarding the exact regulation of insulin gene expression. This is important to further investigate since it will hopefully help us understand the pathophysiology of some types of diabetes. READ MORE

  7. 20. In vitro Studies of β-cell Death and Survival. Modulation by Adenoviral Vectors and Bcl-2 Overexpression

    Author : Andreea Roxana Barbu; Nils Welsh; Decio Eiziric; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cell biology; β-cell; cytokine; mitochondrial membrane potential; Bcl-2; Adenoviral vector; Adenovirus; IFN-α; Diabetes; Cellbiologi; Cell biology; Cellbiologi;

    Abstract : Type 1 diabetes is a multifactorial disease resulting from the selective destruction of insulin-producing β-cells within the pancreatic islets of Langerhans. The mechanisms of β-cell death are not fully understood but cytokines are important mediators of this process. READ MORE
