1. Imaging the pancreas : new aspects on lobular development and adult constitution
Sammanfattning : The mouse pancreas is a mixed exocrine and endocrine glandconsisting of three lobular compartments: the splenic, duodenal and gastric lobes. During embryogenesis, the pancreas forms from two progenitor populations located on the dorsal and ventral side of the primitive gut tube. LÄS MER
2. Studies of Spinal Motor Control Networks in Genetically Modified Mouse Models
Sammanfattning : Spinal neurons are important in several aspects motor control. For example, the neurons essential for locomotor movements reside in the ventral spinal cord. In this thesis, different motor control functions are being related to neuronal populations defined by their common expression of a gene. LÄS MER
3. Gene Expression in the Brains of Two Lines of Chicken Divergently Selected for High and Low Body Weight
Sammanfattning : Artificial divergent selection of chickens for high and low body weight at 8 weeks of age has produced two lines: the high (HWS) and low (LWS) body weight chicken lines. In addition to the difference in body weight, the lines show extreme differences in feeding behaviour and body composition. LÄS MER
4. Bone Morphogenetic Protein Receptors in the Nervous System: Neurotrophic Functions with Emphasis on Catecholaminergic Neurons
Sammanfattning : Members of the transforming growth factor-β (TGF-β) superfamily exhibit a range of effects on a host of different cell types. They signal through heteromeric complexes of serine/threonine kinase receptors of type I and type II. LÄS MER
5. Neurotrophic Factor Receptors in the Normal and Injured Visual System : Focus on Retinal Ganglion Cells
Sammanfattning : The focus of this thesis is the life and death of adult retinal ganglion cells (RGCs). RGCs are neurons that convey visual information from the retina to higher centers in the brain. LÄS MER
