   Sammanfattning : a1-microglobulin is a small glycoprotein present in plasma and in tissues surrounding the gastrointestinal and respiratory tracts. a1-microglobulin is a member of the lipocalin protein family and exhibits several of the typical traits of a lipocalin; it binds an unknown ligand which causes the brown color of the protein, it forms complexes with various different proteins and there have been indications of the presence of a receptor for a1-microglobulin on T-lymphocytes.

3. 12. Hypoxia and differentiation in human neuroblastoma cells

   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ontogeny; embryology human ; Utvecklingsbiologi; teratologi; embryologi människa ; teratology; cytogenetik; Development biology; cytogenetics; Genetik; Genetics; Medicin människa och djur ; HIF; Medicine human and vertebrates ; MYCN; Hypoxia; differentiation; Neuroblastoma;

   Sammanfattning : The childhood tumour neuroblastoma is derived from immature cells of the sympathetic nervous system, which have become arrested at different maturation stages. Neuroblastoma is a malignancy with a high degree of heterogeneity, and there is a correlation between a poor differentiation status and a more aggressive phenotype. LÄS MER

4. 13. Molecular specification of expanded forebrain neural stem and progenitor cells

   Författare :Malin Parmar; Neurobiologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; teratology; ontogeny; embryology human ; Development biology; developmental control genes; in vitro expansion; transplantation; precursor cell; stem cells; progenitor cell; human; mouse; Utvecklingsbiologi; teratologi; embryologi människa ;

   Sammanfattning : The molecular specification of neural precursor cells has been suggested to be a progressive process, with a transition from an early requirement for extrinsic signals to intrinsic mechanisms. Thus, the cells in the nervous system acquire distinct fates in response to extrinsic signals, which activate repertoires of transcription factors in a region and cell type specific manner. LÄS MER

5. 14. Development of the Mouse Lateral Telencephalon

   Författare :Jan Stenman; Institutionen för experimentell medicinsk vetenskap; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; teratologi; embryologi människa ; Utvecklingsbiologi; ontogeny; embryology human ; teratology; Development biology; progenitor domains; striatum; olfactory bulb; amygdala; development; telencephalon; patterning; mouse;

   Sammanfattning : The telencephalon is the most rostral part of the vertebrate central nervous system and is comprised of a number of structures important for voluntary movements and higher cognitive processes. This thesis focuses on the genetic mechanisms that control development of a number of telencephalic structures: the olfactory bulb, the striatum as well as the lateral and basolateral nuclei of the amygdala.

7. 15. Long-term neurogenesis after stroke in the adult rat brain

   Författare :Pär Thored; Lund Neurologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; embryologi människa ; Neurology; neuropsychology; neurophysiology; Utvecklingsbiologi; teratologi; embryology human ; ontogeny; Development biology; teratology; Stroke; Stem Cells; Neurogenesis; neurofysiologi; Clinical biology; Klinisk biologi; Neurologi; neuropsykologi;

   Sammanfattning : Stroke is a leading cause of death and disability for which there is no treatment for functional recovery. Following stroke, striatal neurogenesis is increased, with newly formed neuroblasts migrating towards the damage. This response has so far been considered acute and transient. LÄS MER
