  2. 6. Stem cells and development : studies on SUFU and LGR5

    Author : Maria Hölzl; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Embryonic development and cancer formation appear quite different from each other at first glance, yet they share common characteristics such as the reliance on certain signalling pathways. The Hedgehog (HH) and WNT signalling cascades play key roles in a variety of developmental processes where deregulation of these pathways result in a diversity of birth defects. READ MORE

  4. 7. The role of Lhx2 in hair follicle morphogenesis and regeneration

    Author : Gunilla Törnqvist; Leif Carlsson; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Cell and molecular biology; Cell- och molekylärbiologi; molecular cell biology; molekylär cellbiologi;

    Abstract : Hair is important for thermoregulation, physical protection, sensory activity, seasonal camouflage and social interactions. Hair is produced in hair follicles (HFs), complex mini-organs in the skin devoted to this task. READ MORE

  5. 8. Functions of platelet-derived growth factor-A during organogenesis

    Author : Linda Karlsson; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; platelet-derived growth factor-A; knockout; mouse organogenesis; epithelial-mesenchymalinteractions; skin; hair follicles; CNS; lung; gastrointestinal villus;

    Abstract : The formation of organs during embryonic development is calledorganogenesis. This process is regulated by the genes residing in the genome. READ MORE

  6. 9. A functional genomics approach to PDGF and pericyte biology

    Author : Cecilia Bondjers; Göteborgs universitet; []
    Keywords : PDGF; hair follicle; skin; testis; epithelial-mesenchymal interaction; microarray; pericyte; transgenic mouse;

    Abstract : The rapid expansion of genome sequence data demands for increased efforts and speed concerning functional analysis of gene products. Two approaches to such analysis, namely transgenic technologies and analysis of gene expression have successfully been used to study functions of gene products in complex organisms, such as mammals.

  7. 10. Dynamics of Photoinduced Processes in Dye-Sensitized Nanocrystalline Semiconductor Films--Reactions in the Photoactive Part of the Grätzel Solar Cell

    Author : Gabor Benko; Kemisk fysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; supraledare; magnetisk resonans; spektroskopi; magnetiska och optiska ; egenskaper elektriska; Kondenserade materiens egenskaper:elektronstruktur; spectroscopy; relaxation; magnetic resonance; supraconductors; Kemi; Condensed matter:electronic structure; electrical; femtosecond spectroscopy; solar cells; Chemistry; excited states; photoinduced electron transfer; transition metal complexes; nanocrystalline titanium dioxide; dye sensitization; porous semiconductor film; magnetic and optical properties;

    Abstract : The key materials used to convert solar energy into electricity in the Grätzel-type solar cells are dye molecules and titanium dioxide particles attached to each other. The former are similar to those in common products like purple pigments in blueberry juice, while the latter are like sunscreen, white paint, or toothpaste. READ MORE
