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

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

   Sammanfattning : 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). LÄS MER

3. 2. Manipulating neural stem cells

   Författare :Malin Eriksson; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : The stem cell field is a fairly young but fast growing scientific field. Our understanding of stem cells has changed tremendously over the last couple of decades. This in mainly due to the development of new techniques that has enabled us to study stem cells from a completely new perspective. LÄS MER

4. 3. Neural Stem Cell Differentiation and Migration

   Författare :Anna Erlandsson; Karin Forsberg-Nilsson; Bengt Westermark; Christer Betsholtz; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicine; CNS; stem cells; neuron; PDGF; SCF; differentiation; migration; ERK; Medicin; Dermatology and venerology; clinical genetics; internal medicine; Dermatologi och venerologi; klinisk genetik; invärtesmedicin; Medicinsk biokemi; Medical Biochemistry;

   Sammanfattning : Neural stem cells are the precursors of neurons, astrocytes and oligodendrocytes. During neural development, the division of stem cells takes place close to the lumen of the neural tube, after which they migrate to their final positions within the central nervous system (CNS).

5. 4. Modeling Neural Stem Cell and Glioma Biology

   Författare :Tobias Bergström; Karin Forsberg-Nilsson; Staffan Johansson; Sven Påhlman; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; neural stem cell; integrins; glioma; PDGF; mast cell; Molekylär cellbiologi; Molecular Cellbiology; Oncology; Onkologi;

   Sammanfattning : This thesis is focused on neural stem cell (NSC) and glioma biology. I discuss how NSCs interact with extracellular matrix (ECM) proteins in the stem cell niche, and investigate the consequences of deregulated Platelet-derived growth factor (PDGF) signaling for embryonic NSCs in transgenic mice.

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

   Författare :Lina Dahl; Leif Carlsson; Jan-Ingvar Jönsson; Umeå universitet; []
   Nyckelord :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 ;

   Sammanfattning : 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. LÄS MER
