  1. 1. Heparan Sulfate and Development : A Study of NDST Deficient Mice and Embryonic Stem Cells

    Författare :Katarina Holmborn; Lena Kjellén; Erik Forsberg; Catherine L. Merry; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cell and molecular biology; heparan sulfate; proteoglycan; biosynthesis; N-deacetylase N-sulfotransferase; NDST; gene targeting; embryonic development; lung development; mast cells; Cell- och molekylärbiologi;

    Sammanfattning : Heparan sulfate (HS) proteoglycans consist of sulfated HS chains covalently bound to core proteins. They are ubiquitously expressed, on the cell surface and in the extracellular matrix, throughout the body. LÄS MER

  3. 2. 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.

  4. 3. Functions of Heparan Sulfate During Mouse Development : Studies of Mice with Genetically Altered Heparan Sulfate Biosynthesis

    Författare :Maria Ringvall; Lena Kjellén; Erik Forsberg; Ulf Lindahl; Erika Gustafsson; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Developmental biology; embryonic development; gene targeting; lung development; ossification; heparan sulfate; heparin; N-deacetylase N-sulfaotransferase; NDST; proteoglycan; morphogen; biosynthesis; Utvecklingsbiologi; Developmental biology; Utvecklingsbiologi;

    Sammanfattning : Heparan sulfate (HS) is a ubiquitous polysaccharide on the cell surface and in the extracellular matrix. HS is an important actor in the regulation of cell signaling, especially in the developing embryo. LÄS MER

  5. 4. Stem cell function and organ development : analysis of Lhx2 function in hematopoietic stem cells and eye development

    Författare :Lina Dahl; Leif Carlsson; Jan-Ingvar Jönsson; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Lhx2; hematopoietic system; hematopoietic stem cell; progenitor; embryonic stem cell; embryoid body; eye development; forebrain; eye field transcription factor; Molecular medicine genetics and pathology ; Molekylär medicin genetik och patologi ; molekylär medicin genetik och patologi ; molecular medicine  genetics and pathology ;

    Sammanfattning : When a multicellular organism suffers damages to tissues/organs it heals itself by either substituting the lost cellular matrix by scar formation or by regenerating the lost tissue. Regeneration likely occurs by a recapitulation of the developmental process that formed the organ. LÄS MER

  7. 5. Neuronal Development in the Embryonic Retina : Focus on the Characterization, Generation and Development of Horizontal Cell Subtypes

    Författare :Per-Henrik Edqvist; Finn Hallböök; Steven McLoon; Uppsala universitet; []
    Nyckelord :Neurosciences; Activin; Chick; Follistatin; Interneuron; Isl1; Lim1; Migration; Neurogenesis; Prox1; Transcription factor; Neurovetenskap;

    Sammanfattning : Horizontal cells are retinal interneurons that modulate the output from photoreceptors. Two horizontal cell (HC) subtypes are commonly identified in the vertebrate retina: axon-bearing and axon-less HCs. LÄS MER
