  1. 21. On astrocytes and neural stem cells : a study of reactive and canonical neurogenesis

    Författare :Margherita Zamboni; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The mammalian central nervous system has limited regenerative capacity and the long-lasting functional impairment resulting from trauma and neurodegenerative disease derives from a failure to repopulate neuronal cell populations that are lost to injury. The studies included in the present thesis aim at proposing astrocytes as a novel source for achieving widespread replacement of neurons. LÄS MER

  3. 22. An ependymal cell quest : identification and functional role of spinal cord neural stem cells

    Författare :Hanna Sabelström; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Few injuries have as profound and long-lasting consequences as spinal cord injury. The primary areas of impaired function typically include sensation, mobility, bladder, bowel and sexual function. The economic, social and personal effects can also be devastating. LÄS MER

  4. 23. Calcium signaling in neurogenesis: regulation of proliferation, differentiation and migration of neural stem cells

    Författare :Paola Rebellato; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The calcium ion (Ca2+) is a highly versatile and ubiquitous signaling messenger in all cell types. Signal transduction occurs through changes in the cytosolic Ca2+ concentration after the opening of Ca2+ channels in the plasma membrane (PM) and endoplasmic reticulum (ER). LÄS MER

  5. 24. Time-Lapse Bright-Field Microscopy and Image Acquisition of In-Vitro Neural Stem Cells

    Författare :Johan Degerman; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : This project involves development of a system for time-lapse image acquisition of neural stem cells. The purpose of analyzing time sequences is to find migrational patterns that are characteristic for different cell types. LÄS MER

  7. 25. Single-cell analysis of mammalian cardiogenesis elucidating an essential role of outflow tract progenitors

    Författare :Chikai Zhou; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The heart is the first organ to form and start to function during mammalian embryogenesis. This complex organ system is constructed by a diverse set of cell types, involving mesodermal precursors and heart progenitors, at the earliest embryonic stages. LÄS MER
