  1. 21. 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

  3. 22. Characterization of New Players in Planar Polarity Establishment in Arabidopsis

    Författare :Stefano Pietra; Markus Grebe; Niko Geldner; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; SABRE; planar polarity; CLASP; cell division orientation; microtubule cytoskeleton; actin; AIP1; patterning; Developmental Biology; miljömedicinsk utvecklingsbiologi;

    Sammanfattning : Coordinated polarity and differentiation of cells in the plane of a tissue layer are essential to the development of multicellular organisms. Arabidopsis thaliana root hairs and trichomes provide model systems to study the pathways that control planar polarity and cell fate specification in plants. LÄS MER

  4. 23. Modulation of retinal progenitors : A bird’s-eye view of retinal regeneration and disease

    Författare :Dardan Konjusha; Finn Hallböök; Rusty Lansford; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Developmental neurobiology; Retinoblastoma; MYCN; Cone photoreceptor; Nolz1; Endothelin; Müller cells;

    Sammanfattning : The cell populations of the retina and their intricate organization provide us with one of the most important senses – vision. All retinal cell populations are derived from a common progenitor pool as a result of tight regulation of proliferation, differentiation, dedifferentiation, and programmed cell death. LÄS MER

  5. 24. Chromatin Insulators and CTCF: Architects of Epigenetic States during Development

    Författare :Rituparna Mukhopadhyay; Rolf Ohlsson; Karim Malik; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Developmental biology; DNA methylation; CTCF; Chromatin insulators; Microarray; Utvecklingsbiologi; Developmental biology; Utvecklingsbiologi;

    Sammanfattning : A controlled and efficient coordination of gene expression is the key for normal development of an organism. In mammals, a subset of autosomal genes is expressed monoallelically depending on the sex of the transmitting parent, a phenomenon known as genomic imprinting. LÄS MER

  7. 25. Control of early development of the lens and the retina

    Författare :Tanushree Pandit; Lena Gunhaga; Paola Bovolenta; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Lens; retina; BMP; FGF; chick; Developmental Biology; miljömedicinsk utvecklingsbiologi;

    Sammanfattning : The nervous system is composed of two separate compartments, the central and the peripheral nervous system. The peripheral nervous system (PNS) composed mainly of sensory organs transmits sensory information to the central nervous system (CNS) comprising the brain and the spinal cord. LÄS MER
