2. 1. Genetic pathways controlling CNS development : The role of Notch signaling in regulating daughter cell proliferation in Drosophila

   Author : Caroline Bivik Stadler; Stefan Thor; Jan-Ingvar Jönsson; Allison Bardin; Linköpings universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

   Abstract : The human central nervous system (CNS) displays the greatest cellular diversity of any organ system, consisting of billions of neurons, of numerous cell sub-types, interconnected in a vast network. Given this enormous complexity, decoding the genetic programs controlling the multistep process of CNS development remains a major challenge. READ MORE

4. 2. Genetic mechanisms regulating proliferation and cell specification in the Drosophila embryonic CNS

   Author : Shahrzad Bahrampour; Stefan Thor; Jan-Ingvar Jönsson; Simon Sprecher; Linköpings universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

   Abstract : The central nervous system (CNS) consists of an enormous number of cells, and large cellular variance, integrated into an elaborate network. The CNS is the most complex animal organ, and therefore its establishment must be controlled by many different genetic programs. READ MORE

5. 3. Novel Insights into Haematopoietic Stem Cell Regulation and Function

   Author : Sarah Warsi; Avdelningen för molekylärmedicin och genterapi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Haematopoiesis; Haematopoietic stem cell; Stem cell regulation; Haematopoietic stem cell transplantation;

   Abstract : The haematopoietic stem cell (HSC) is a somatic stem cell essential for life long haematopoiesis; HSCs have the capability to differentiate into all mature types of blood cells and can also undergo self-renewal to maintain their own numbers. They also have the potential to reconstitute a complete haematopoietic system following HSC transplantation, also known as bone marrow transplantation, which is used to treat many haematopoietic disorders.

6. 4. New Approaches for Chemical Analysis of Single Cells and Vesicles

   Author : Johan Dunevall; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Electrochemistry; Analytical chemistry; Chemistry; Exocytosis; Catecholamines;

   Abstract : Exocytosis is the major cell-to-cell communication process in the nervous system, involving the conversion of an electrical signal (e.g. action potential) to a chemical one. Signaling molecules like neurotransmitters, hormones and/or peptides are stored in vesicles inside the cell. READ MORE

7. 5. Regulatory programs controlling profileration during Drosophila nervous system development

   Author : Erika Gunnar; Stefan Thor; Jan-Ingvar Jönsson; Udo Häcker; Linköpings universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

   Abstract : The central nervous system (CNS) is the most complex organ in the body, responsible for complex functions, including thinking, reasoning and memory. The CNS contains cells of many different types, often generated in vast numbers. READ MORE
