1. 6. Neural Stem and Progenitor Cells as a Tool for Tissue Regeneration

   Författare :Ulrika Wallenquist; Karin Forsberg Nilsson; Lars Hillered; Karin Holmqvist; Anders Lewén; Johan Bengzon; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; traumatic brain injury; neural stem cells; transplantation; CNS; PNS; progenitor cells; inflammation; CCI; Biochemistry; Biokemi; Neurosurgery; neurokirurgi; Medical Biochemistry; medicinsk biokemi;

   Sammanfattning : Neural stem and progenitor cells (NSPC) can differentiate to neurons and glial cells. NSPC are easily propagated in vitro and are therefore an attractive tool for tissue regeneration. Traumatic brain injury (TBI) is a common cause for death and disabilities. A fundamental problem following TBI is tissue loss. LÄS MER

3. 7. Mechanisms of survival and maintenance of Hematopoietic Stem Cells and Multipotent Progenitor Cells

   Författare :Richard Karlsson; Institutionen för translationell medicin; []
   Nyckelord :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;

   Sammanfattning : 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. LÄS MER

4. 8. Stem and progenitor cells in brain ad breast malignancies

   Författare :Gabriella Honeth; Bröstcancer-genetik; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neural progenitor cells; glioma; migration; chemokines; cancer stem cells; breast cancer; CD44; CD24;

   Sammanfattning : Stem cells have qualities that clearly distinguish them from all other cells. Capabilities like self-renewal, differentiation and migration make them truly powerful. This thesis deals with different aspects of stem/progenitor cells in relation to cancer. LÄS MER

5. 9. Molecular specification of expanded forebrain neural stem and progenitor cells

   Författare :Malin Parmar; Neurobiologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; teratology; ontogeny; embryology human ; Development biology; developmental control genes; in vitro expansion; transplantation; precursor cell; stem cells; progenitor cell; human; mouse; Utvecklingsbiologi; teratologi; embryologi människa ;

   Sammanfattning : The molecular specification of neural precursor cells has been suggested to be a progressive process, with a transition from an early requirement for extrinsic signals to intrinsic mechanisms. Thus, the cells in the nervous system acquire distinct fates in response to extrinsic signals, which activate repertoires of transcription factors in a region and cell type specific manner. LÄS MER

7. 10. In vivo and in vitro approaches to induce beta cells from stem and progenitor cells

   Författare :Lars Selander; Helena Edlund; Yuval Dor; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; pancreas; stem cell; progenitor; beta cell; in vitro; Molecular medicine genetics and pathology ; Molekylär medicin genetik och patologi ; molecular medicine medical sciences ; molekylär medicin medicinska vetenskaper ;

   Sammanfattning : Diabetes or diabetes mellitus which is the correct medical term is a medical condition were the affected person lack the ability to regulate his or her blood glucose levels. This inability is directly due to the fact that the insulin producing cells, residing in the pancreas, can’t meet the body’s demand for insulin. LÄS MER
