1. In vivo properties of neural stem cells after transplantation into the rat brain-Studies of phenotypic differentiation and functional integration using cell-specific labelling and electrophysiological techniques
Sammanfattning : In the present thesis, we have examined the in vivo properties of in vitro expanded human and rat neural stem-and progenitor cells after transplantation into the neonatal and adult rat brain. The survival and differentiation of the grafted cells were assessed using species-specific antisera, and pre-labelling with the reporter gene green fluorescent protein (GFP). LÄS MER
2. Molecular Mechanisms in Endothelial Cell Differentiation
Sammanfattning : Angiogenesis is the formation of new blood vessels from the pre-existing blood vessels. Blood vessels are composed of endothelial cells and supporting musculature. Angiogenesis is regulated by numerous soluble ligands and by cell-matrix interactions. LÄS MER
3. Blood in a Lab: Using Immortalized Erythroid Cell Lines as a Source for Blood Transfusion
Sammanfattning : .... LÄS MER
4. Use of neural progenitor cell lines and astrocytes for transplantation and gene transfer to the CNS
Sammanfattning : Intracerebral neuronal transplantation have been shown to ameliorate symptoms of brain dysfunction in both animals models and Parkinson's disease, although problems still remain. The newly introduced technique of ex vivo gene transfer could serve as an alternative approach, possible avoiding some of the draw-backs of the embryonal tissue used in neuronal grafting. LÄS MER
5. Modulation of the deubiquitnating system during lymphoid cell activation and viral infection
Sammanfattning : The family of ubiquitin-specific proteases (USPs) removes ubiquitin from its conjugates and regulates the production and recycling of ubiquitin. USPs are thereby critically involved in the control of important functions such as cell growth, differentiation and apoptosis. Increasing evidence implicates USPs deregulation in malignant transformation. LÄS MER
