  1. 1. Wnt signalling in the development of ventral midbrain dopaminergic neurons

    Författare :Gonçalo de Sá e Sousa de Castelo-Branco; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Dopaminergic Neuron; Ventral Midbrain Development; Writs; Dickkopf; beta-catenin; GSK-3beta; Stem Cells; Neural Precursors;

    Sammanfattning : Dopaminergic (DA) neurons in the ventral midbrain (VM) are one of the major cell types lost in Parkinson's disease (PD). Proof-of-principle exists for cell replacement therapies for PD, but wider application is halted by the unavailability of abundant sources of DA neurons. Stem cells might constitute one of these sources. LÄS MER

  2. 2. Wnt signaling and metaphyseal bone healing

    Författare :Fredrik Agholme; Per Aspenberg; Lars Nordsletten; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : This thesis relates to some new aspects on the regulation of bone healing. In the last few years, Wnt-signaling has been shown to play a central role in bone biology. As well as being involved in bone maintenance and repair, Wnt-signaling has been presented as one of the key pathways through which bone responds to mechanical load. LÄS MER

  3. 3. 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. 4. The Wnt pathway in ventral midbrain dopaminergic differentiation

    Författare :Diogo Ribeiro; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Parkinson’s disease (PD) is a debilitating neurodegenerative disease in which dopaminergic (DA) neurons in the substantia nigra are lost. Current treatments such as administration of levodopa (L-DOPA) are initially effective but the disease eventually progresses, highlighting the need for a treatment that restores and maintains the otherwise lost functions.
