  2. 21. Stem cell fate regulation: computational modeling in the hematopoietic system

    Author : José Teles; Beräkningsbiologi och biologisk fysik - Genomgår omorganisation; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; stochastic modeling; dynamical modeling; gene regulation; hematopoiesis; cell fate; stem cells; Fysicumarkivet A:2012:Teles;

    Abstract : The ability to sense the surrounding environment and respond to external fluctuations is a fundamental property of cells, the basic unit of life. Although cells can be very different in their composition and structure, they all have specialized molecular mechanisms that allow them to adapt to their environment, by coordinating gene expression and protein production.

  4. 22. On the origin of B cells. Elucidating the Role of Tyrosine Kinase Receptors in B Cell Development

    Author : Alya Zriwil; Avdelningen för molekylär hematologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Hematopoiesis; B cell development; cytokine; tyrosine kinase receptors;

    Abstract : B cells are essential cells that are part of the adaptive immune system with the capacity to produce antibodies against exogenous antigens. These cells are produced through a process called hematopoiesis, tightly regulated by extrinsic and intrinsic factors. READ MORE

  5. 23. Long bone growth and evolution revealed by three-dimensional imaging

    Author : Jordi Estefa; Sophie Sanchez; Per Ahlberg; Holly Woodward; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; 3D histology; hematopoiesis; humerus; tetrapods; Biologi; Biology;

    Abstract : Propagation phase-contrast synchrotron radiation microtomography is a non-destructive method used for studying histology in three dimensions (3D). Using it, the 3D organization of the diaphyseal cortical vascularization in the humerus of two seymouriamorphs was analyzed in this thesis. READ MORE

  6. 24. Mechanisms of survival and maintenance of Hematopoietic Stem Cells and Multipotent Progenitor Cells

    Author : Richard Karlsson; Institutionen för translationell medicin; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; extracellulära vätskor; Hematologi; extracellular fluids; Haematology; hypoxia.; forkhead; Akt PKB; Bcl-2; apoptosis; Flt3; FL; c-kit; KL; cytokines; Hematopoiesis; progenitor;

    Abstract : Hematopoietic stem cells and progenitor cells are maintained in the bone marrow microenvironment, where factors including soluble and membrane-bound cytokines influence the processes of self-renewal, proliferation and differentiation. Two nonreduntant cytokines with effects on hematopoiesis, Kit Ligand (KL) and Flt3 Ligand (FL), signal via related tyrosine kinase receptors, c-kit and Flt3. READ MORE

  7. 25. Molecular regulation of hematopoietic stem cells

    Author : David Bryder; Avdelningen för molekylär hematologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Hematologi; extracellulära vätskor; extracellular fluids; Haematology; bone marrow transplantation; cytokines; Hematopoiesis; stem cells;

    Abstract : Hematopoietic stem cells (HSCs) are ultimately responsible for the all mature blood cell production. They can primarily be found in the bone marrow (BM) at a low frequency (~0.02%). READ MORE
