2. 1. Stem cell function and organ development : analysis of Lhx2 function in hematopoietic stem cells and eye development

   Author : Lina Dahl; Leif Carlsson; Jan-Ingvar Jönsson; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Lhx2; hematopoietic system; hematopoietic stem cell; progenitor; embryonic stem cell; embryoid body; eye development; forebrain; eye field transcription factor; Molecular medicine genetics and pathology ; Molekylär medicin genetik och patologi ; molekylär medicin genetik och patologi ; molecular medicine  genetics and pathology ;

   Abstract : When a multicellular organism suffers damages to tissues/organs it heals itself by either substituting the lost cellular matrix by scar formation or by regenerating the lost tissue. Regeneration likely occurs by a recapitulation of the developmental process that formed the organ. READ MORE

4. 2. Live and Let Die : Critical regulation of survival in normal and malignant hematopoietic stem and progenitor cells

   Author : Pernilla Eliasson; Jan-Ingvar Jönsson; Mikael Sigvardsson; Urban Gullberg; Linköpings universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; hematopoietic stem cells; hypoxia; self-renewal; survival; acute myeloid leukemia; FLT3; Cell and molecular biology; Cell- och molekylärbiologi; Haematology; Hematologi;

   Abstract : The hematopoietic stem cell (HSC) is characterized by its ability to self-renew and produce all mature blood cells throughout the life of an organism. This is tightly regulated to maintain a balance between survival, proliferation, and differentiation. READ MORE

5. 3. Neural Stem and Progenitor Cells : Cellular Responses to Known and Novel Factors

   Author : Jimmy Larsson; Karin Forsberg-Nilsson; Ola Hermanson; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; neural stem cell; differentiation; proliferation; migration; PDGF; SCF; NRBP2; medulloblastoma; Biochemistry; Biokemi; Medical Biochemistry; Medicinsk biokemi;

   Abstract : Neural stem cell self-renewal and differentiation are tightly regulated events during CNS development, leading to cell division into new neural stem cells or the formation of neurons and glial cells. This thesis focuses on the cellular responses induced by known and novel factors in neural stem and progenitor cells (NSPCs). READ MORE

6. 4. Hematopoietic stem and progenitor cells and potentials for application in fetal cell replacement therapy

   Author : Karina Liuba; Lund Obstetrik och gynekologi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; in utero hematopoietic cell transplantation; hematopoietic stem cell; multipotent progenitor; fetal therapy; heterotypic cell fusion;

   Abstract : Fetal cell replacement therapy or in utero hematopoietic cell transplantation (IUHCT) is proposed as a non-myeloablative alternative to bone marrow transplantation (BMT) for a number of inborn immunologic, hematologic and metabolic disorders. IUHCT represents the method through which variable amounts of natural or genetically modified hematopoietic cells can be transferred to the fetal recipient in hope of correcting the disorder and preventing postnatal permanent organ damage.

7. 5. 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
