1. 1. Regulation of Apoptosis in Hematopoietic Progenitor Cells: Involvement of Different Signaling Pathways

   Författare :Maria Kraft; Institutionen för translationell medicin; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cytokines; apoptosis; cell cycle; c-Kit; Flt3; Flt3-ITD; Akt; Bcl-2; FoxO3; mouse; hematopoiesis; progenitor;

   Sammanfattning : Proliferation, differentiation, and survival of hematopoietic stem cells and multipotent progenitor cells are regulated by cytokines and cell-cell interactions. Kit ligand (KL) and Flt3 ligand (FL) have pleiotropic effects, promotes survival, but are nonredundant. LÄS MER

3. 2. 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. 3. 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

5. 4. Transposable Elements in Neural Progenitor Cells

   Författare :Liana Fasching; Molekylär neurogenetik; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Transposable Elements; TRIM28; Epigenetic Regulation; Gene Expression; Neural Progenitor Cells;

   Sammanfattning : More than 90% of DNA does not code for proteins and for a long time these sequences were referred to as “junk DNA” due to their unknown purpose. With the advent of new technologies it is now known, that the non-coding part of the genome is of great importance for regulating gene expression and is therefore indispensable. LÄS MER

7. 5. Features of adult neural progenitor cells

   Författare :Lisa Arvidsson; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :adult neural progenitor cell;

   Sammanfattning : The adult Central Nervous System (CNS) harbors neural progenitor cells (NPCs) in three areas: the subventricular zone (SVZ) of the lateral ventricles and the subgranular zone in the hippocampus and around the central canal in the spinal cord. The NPCs can be isolated and cultured in vitro. LÄS MER
