2. 1. Creating cell microenvironments in vitro

   Author : Patric Wallin; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cell migration; lipid bilayers; cell differentiation; liquid handling; surface functionalization; Microfluidics; chemotractant gradients; mammalian cell culture; cell microenvironments; in vitro screening assay;

   Abstract : Stem cells have a great potential to bring about advancements in fields like developmental biology, drug discovery, cancer biology and tissue engineering. In order to be able to use stem cells to their full potential, it is important to have control over their behavior. READ MORE

4. 2. Genetic Mechanisms during Terminal Cell Fate Specification in the Drosophila CNS

   Author : Johannes Stratmann; Stefan Thor; Jan-Ingvar Jönsson; Christos Samakovlis; Linköpings universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

   Abstract : Specification of the many unique neuronal subtypes found in the nervous system depends on spatiotemporal cues and terminal selector cascades, mostly acting in sequential combinatorial codes of transcription factors (TFs) to dictate cell fate. Out of 10,000 cells in the Drosophila embryonic ventral nerve cord (VNC), only 28 cells selectively express Nplp1. READ MORE

5. 3. Cell fate specification by Ras-mediated cell signalling in C. elegans

   Author : Teresa Tiensuu; Simon Tuck; Benjamin Podbilewicz; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Cell and molecular biology; cell signalling; Ras; vulva precursor cell; lin-25; sur-2; lin-1; cell fate specification; Mediator; vulva induction; transcriptional regulation; Cell- och molekylärbiologi; Cell and molecular biology; Cell- och molekylärbiologi;

   Abstract : Induction of vulval fates in the C. elegans hermaphrodite is mediated by a conserved RTK/Ras/MAP kinase signalling pathway, in which the core components can be placed into a linear genetic and biochemical pathway. However, the events that occur downstream of this pathway are not yet well understood. READ MORE

6. 4. Cellular and Molecular Pathways Governing Hematopoietic Stem Cell Fate

   Author : Liping Yang; Stamcellscentrum (SCC); []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; stem cell; hematopoiesis; bone marrow transplantation; lineage commitment; cytokine; Medicine human and vertebrates ; Clinical genetics; Klinisk genetik; extracellulära vätskor; Hematologi; Medicin människa och djur ; extracellular fluids; Haematology;

   Abstract : Hematopoietic Stem Cells (HSCs) have been defined to have abilities of both self-renewal and multi-lineage differen-tiation. The balance between these abilities is rigorously controlled under steady-state status (homeostasis) and when the normal processes of self-renewal and differentiation become deregulated, a disorder of blood system (such as leukemias) can occur.

7. 5. Molecular Studies of Mast Cell Migration and Apoptosis : Two Ways of Regulating Mast Cell Numbers at Sites of Inflammation

   Author : Jessica Alfredsson; Gunnar Nilsson; Hans-Uwe Simon; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pathology; mast cell; SCF; IL-3; FcεRI; migration; apoptosis; Bim; Bcl-2; Bcl-XL; Akt; FOXO; MAPK; Patologi; Pathology; Patologi;

   Abstract : Upon activation mast cells release numerous proinflammatory mediators. With this feature, mast cells play an important role in host defense against pathogens, and are involved in tissue remodeling and wound healing. However, in cases of excessive inflammation the effects of mast cells are detrimental. READ MORE
