  1. 1. Molecular and functional anatomy of the mouse olfactory epithelium

    Författare :Viktoria Vedin; Anna Berghard; Urban Lendahl; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; olfactory epithelium; odorant receptor; zone; odorant; gene expression; cell specification; c-Fos; dichlobenil; olfactometry; proliferation; Molecular biology; Molekylärbiologi;

    Sammanfattning : The olfactory system is important for social behaviors, feeding and avoiding predators. Detection of odorous molecules is made by odorant receptors on specialized sensory neurons in the olfactory epithelial sheet. LÄS MER

  3. 2. The Role of Lhx2 During Organogenesis : - Analysis of the Hepatic, Hematopoietic and Olfactory Systems

    Författare :Åsa Kolterud; Leif Carlsson; Stefan Thor; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Developmental biology; LIM-homeobox gene; Lhx2; fetal liver; hepatic stellate cells; hematopoietic stem cells; septum transversum; self-renewal; odorant receptor genes; olfactory epithelium; olfactory sensory neuron; Utvecklingsbiologi; Developmental biology; Utvecklingsbiologi; molekylärbiologi; Molecular Biology;

    Sammanfattning : During embryonic development a variety of tissues and organs such as the lung, eye, and kidney are being formed. The generation of functional organs is regulated by reciprocal cell-cell interactions. Via the secretion of soluble molecules one type of cells affect the fate of their neighboring cells. LÄS MER

  4. 3. Zonal organization of the mouse olfactory systems

    Författare :Fredrik Gussing; Staffan Bohm; Anna Berghard; Diego Restrepo; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Molecular biology; olfactory; vomeronasal; gene expression; zone; organization; behavior; Molekylärbiologi; Molecular biology; Molekylärbiologi; molekylärbiologi; Molecular Biology;

    Sammanfattning : Animals survey their environment for relevant odorous chemical compounds by means of the olfactory system. This system is in most vertebrates divided into a main and accessory olfactory system with two specialized neuroepithelia, the olfactory and the vomeronasal epithelium, respectively. LÄS MER

  5. 4. Effects of retinoic acid in the mouse olfactory sensory systems

    Författare :Maria Hörnberg; Staffan Bohm; Finn Hallböök; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; olfactory; retinoic acid; neuron survival; Molecular biology; Molekylärbiologi;

    Sammanfattning : A common characteristic in neurodegenerative diseases of the brain is death of specific neuronal populations. The lack of neuron proliferation and axon extension in most parts of the central nervous system leads to chronic loss of neurons in the case of injury or disease. LÄS MER

  7. 5. Vitamin A regulated neuronal regeneration and homeostasis

    Författare :Sofia Håglin; Anna Berghard; Staffan Bohm; Leif Carlsson; Ola Hermanson; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Activity dependent; Adult stem cells; Ageing; CYP26B1; Homeostasis; Metaplasia; Neurogenesis; Olfactory epithelium; Regeneration; Respiratory epithelium; Retinoic acid; Sensory map; Vitamin A;

    Sammanfattning : The olfactory epithelium is a dynamic tissue maintained by continuous neurogenesis throughout life. Upon injury, neurons and other olfactory cell types are regenerated through proliferation of horizontal stem cells. Some genes that regulate vitamin A metabolism are spatially expressed in the olfactory epithelium. LÄS MER
