  1. 16. Long bone growth and evolution revealed by three-dimensional imaging

    Författare :Jordi Estefa; Sophie Sanchez; Per Ahlberg; Holly Woodward; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; 3D histology; hematopoiesis; humerus; tetrapods; Biologi; Biology;

    Sammanfattning : Propagation phase-contrast synchrotron radiation microtomography is a non-destructive method used for studying histology in three dimensions (3D). Using it, the 3D organization of the diaphyseal cortical vascularization in the humerus of two seymouriamorphs was analyzed in this thesis. LÄS MER

  2. 17. Root system of seabuckthorn (Hippophaë rhamnoides L.) : morphology, metabolism and gene expression

    Författare :Syed Rehmat Ullah Shah; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Nutrient availability is one of the limiting factors for plant growth and development, and the nutrients on Earth are unevenly distributed. To overcome this, plants adapt by modifying their morphology and physiology, especially of the root system. Seabuckthorn is a small tree growing in temperate regions of Europe and Asia. LÄS MER

  3. 18. Swimming with the current : Fictive locomotion reveals subtle phenotypes in the zebrafish locomotor network

    Författare :Harmen Kornelis Koning; Henrik Boije; David McLean; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; dmrt3a; wt1a; spinal cord; Mauthner cell; neural development; locomotor network; zebrafish;

    Sammanfattning : Neural networks are the functional building blocks of the central nervous system. To better understand how these networks develop and operate, we turned to the zebrafish locomotor network, with a focus on subtypes of interneurons expressing dmrt3a and wt1a. LÄS MER

  4. 19. Metabolomics and wood development : catching a metabolome

    Författare :Annika Johansson; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The tree industry is one of Sweden's most important economic sectors, producing pulp, paper, wooden goods and wood as a bioenergy source. Understanding the biology behind the processes of tree growth and wood development is a key to maximizing the use of wood as raw material. LÄS MER

  5. 20. From endothelial cells to the vascular network : How cell migration and proliferation are orchestrated to build lymphatic vessels

    Författare :Di Peng; Katarzyna Koltowska; Vermot Julien; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Lymphangiogenesis; Cell migration; Zebrafish; Biologi med inriktning mot zoologisk utvecklingsbiologi; Biology with specialization in Animal Development;

    Sammanfattning : Lymphatic endothelial cells (LECs) migrate across body to form a branched network, which is crucial for fluid drainage and immune cell trafficking of the tissues. However, the molecular mechanisms behind the spatiotemporal regulation and fine-tuning of LEC migration remain largely unknown. LÄS MER
