  1. 1. Early Blood Cell Formation "in sickness and health, ´till death do us part"

    Författare :Kees-Jan Pronk; Immunologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Hematopoietic stem cell; differentiation; regulation; myeloerythropoeisis; myelopoesis; p16INK4A; aging; tumor necrosis factor;

    Sammanfattning : Hematopoietic stem cells (HSC), the ancestors of all blood cells, have the ability to give rise to mature effector cells through a series of developmental steps. This is a tightly regulated, though a highly dynamic process: on the one hand, dysregulation in steady-state could lead to under- or overgrowth of certain blood cell lineages, whereas, on the other hand, demands for certain mature blood cells can change dramatically in cases like bleeding and infections.

  2. 2. Regulation of Hematopoietic Stem Cells

    Författare :Emma Rörby; Avdelningen för molekylärmedicin och genterapi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Hematopoiesis; hematopoietic stem cells; hematopoietic stem cell expansion; cord blood; transforming growth factor beta; Smad signaling; pigment epithelium derived factor; CD9;

    Sammanfattning : This thesis is about the regulation of hematopoietic stem cells (HSCs) that represent rare cells residing in the bone marrow (BM) of adults. They are multipotent cells that have the capacity to differentiate to all mature cells of the blood system and have the capacity to self-renew, i.e. generate new HSCs. LÄS MER

  3. 3. Modeling Human Hematopoiesis Using the CRISPR/Cas9 System

    Författare :Alexandra Bäckström; Avdelningen för molekylärmedicin och genterapi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Hematopoiesis; Hematopoietic stem and progenitor cells; HSC regulation; CRISPR Cas9; Gene editing;

    Sammanfattning : Hematopoietic stem cells (HSCs) have the ability to self-renew and to give rise to all blood cells of the different lineages, and are thereby responsible for the replenishment of blood cells throughout life. These cells are tightly regulated by extrinsic and intrinsic regulators, such as signals from the bone marrow microenvironment, complex transcription factor networks and epigenetic regulators.

  4. 4. HOST EPIGENETIC REGULATOR BMI1 AND VIRAL FIBER PROTEIN FOR EQUILIBRIUM BETWEEN ADENOVIRUS AND HOST

    Författare :Manli Na; Neurokirurgi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Adenovirus; BMI1; Dual-gene expression; Epigenetic; Equilibrium; Fiber; HSC; HDAC; TSA;

    Sammanfattning : Human adenoviruses (Ads) are broadly used in cancer gene therapy, vaccine development and gene delivery. The modified Ad5 or Ad2 viruses have been successfully used as oncolytic agents in pre-clinical studies. However they could not be translated into clinic utility due to a number of limitations including inefficient Ad spread among tumor cells. LÄS MER

  5. 5. Development of adenoviral vectors for monitoring telomerase activity in living cells

    Författare :Anna Edqvist; Neurokirurgi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; cytogenetics; Genetics; cancer; onkologi; Cytologi; cancerology; oncology; Cytology; GBM; HSC; adenovirus; hTERT; Genetik; cytogenetik;

    Sammanfattning : ABSTRACT Telomerase activity is a potential molecular marker for cancer and primitive cells in regenerative tissues. The most commonly used method to measure telomerase activity in cells is the telomerase reverse amplification protocol (TRAP) assay, where the protein extracts derived from homogenized cells are analysed.
