  2. 1. Development of the Mouse Lateral Telencephalon

    Author : Jan Stenman; Institutionen för experimentell medicinsk vetenskap; []
    Keywords : 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;

    Abstract : 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.

  4. 2. Hypoxia and differentiation in human neuroblastoma cells

    Author : Helén Nilsson; Institutionen för translationell medicin; []
    Keywords : 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;

    Abstract : 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. READ MORE

  5. 3. Studies on chondrocyte integrins and mechanical signaling

    Author : Karin Holmvall; Institutionen för experimentell medicinsk vetenskap; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; teratology; Development biology; collagen; mechnaical stimulation; cartilage; development; chondrocyte; integrin; ontogeny; embryology human ; Utvecklingsbiologi; teratologi; embryologi människa ;

    Abstract : Integrins are a family of cell surface receptors known to bind matrix proteins and to mediate signals such as mechanical signals between the cell and the surrounding matrix. We have studied integrins that are expressed by chondrocytes, with specific focus on the integrins that interact with the cartilage matrix protein collagen type II. READ MORE

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

    Author : Malin Parmar; Neurobiologi; []
    Keywords : 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 ;

    Abstract : 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.

  7. 5. Structural and evolutionary studies of a lipocalin: the alpha1-microglobulin protein and its gene

    Author : Annika Lindqvist; Institutionen för experimentell medicinsk vetenskap; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; embryology human ; ontogeny; teratology; AMBP; Development biology; protein HC; bikunin; Utvecklingsbiologi; teratologi; embryologi människa ; Genetics; cytogenetics; Genetik; cytogenetik;

    Abstract : 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.
