  2. 1. Heparan Sulfate Regulation of Fibroblast Growth Factor (FGF) Receptor-1 Signal Transduction

    Author : Lars Lundin; Lena Claesson-Welsh; Marco Presta; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pathology; FGF; FGFR; dimerisation; signal transduction; heparan sulfate; proteoglycan; heparin; VEGF; embryonal stem cell; endothelial cell; differentiation; Patologi; Pathology; Patologi;

    Abstract : Fibroblast growth factors (FGFs) constitute a family (currently FGF-1 to FGF-23) of polypeptides that are essential in embryonal development and adult physiology, in animals from nematodes to humans. FGFs bind to four receptor tyrosine kinases, denoted FGFR-1 to FGFR-4. READ MORE

  4. 2. Lineage commitment to a T

    Author : Sidinh Luc; Stamcellscentrum (SCC); []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Hematopoietic stem cell; hematopoiesis; lineage commitment; lymphoid-primed multipotent progenitor;

    Abstract : he hematopoietic development is a highly dynamic but tightly regulated process. The flexibility to produce blood cells through more than one route will allow the blood system to respond rapidly in stress situations such as infections. READ MORE

  5. 3. In vivo properties of neural stem cells after transplantation into the rat brain-Studies of phenotypic differentiation and functional integration using cell-specific labelling and electrophysiological techniques

    Author : Ulrica Englund Johansson; Peter Eriksson; Lund Oftalmologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cell line; Neurology; neuropsychology; neurophysiology; Neurologi; neuropsykologi; neurofysiologi; functional integration; electrophysiology; retrograde tracing; immortalized; GFP; migration; axonal projections; glia; neuron; transplantation; stem cell. progenitor cell; CNS; Biomedical Sciences;

    Abstract : In the present thesis, we have examined the in vivo properties of in vitro expanded human and rat neural stem-and progenitor cells after transplantation into the neonatal and adult rat brain. The survival and differentiation of the grafted cells were assessed using species-specific antisera, and pre-labelling with the reporter gene green fluorescent protein (GFP). READ MORE

  6. 4. Pluripotent Stem Cells of Embryonic Origin : Applications in Developmental Toxicology

    Author : Måns Jergil; Lennart Dencker; Aldert Piersma; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Embryonic stem cell; Microarray; Toxicogenomics; Valproic acid; Developmental toxicology; Teratogenicity; Neural tube defects; Histone deacetylase inhibitor; In vitro toxicology; Toxicology; Toxikologi; Toxicology; Toxikologi;

    Abstract : General toxicity evaluation and risk assessment for human exposure is essential when developing new pharmaceuticals and chemicals. Developmental toxicology is an important part of this risk assessment which consumes large resources and many laboratory animals. READ MORE

  7. 5. Characterization of human dopaminergic neurons in the developing mesencephalon and upon differentiation of stem cells- for replacement therapy in Parkinson´s disease

    Author : Jenny Nelander Wahlestedt; Utvecklings- och regenerativ neurobiologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Parkinson´s disease; stem cells; ventral mesencephalon; dopaminergic neurons; cell replacement therapy; human fetal tissue; radial glia; microRNA; BAC recombineering; reporter cell lines;

    Abstract : Cell-replacement therapy is a promising approach for treating patients with Parkinson ́s disease (PD). For this purpose, there is a need for developing a protocol that can generate high numbers of human transplantable mesencephalic dopaminer- gic (mesDA) neurons. READ MORE
