1. Heparan Sulfate Regulation of Fibroblast Growth Factor (FGF) Receptor-1 Signal Transduction
Sammanfattning : Fibroblast growth factors (FGFs) constitute a family (currently FGF-1 to FGF-23) of polypeptides that are essential in embryonal development and adult physiology, in animals from nematodes to humans. FGFs bind to four receptor tyrosine kinases, denoted FGFR-1 to FGFR-4. LÄS MER
2. Lineage commitment to a T
Sammanfattning : he hematopoietic development is a highly dynamic but tightly regulated process. The flexibility to produce blood cells through more than one route will allow the blood system to respond rapidly in stress situations such as infections. LÄS MER
3. 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
4. Pluripotent Stem Cells of Embryonic Origin : Applications in Developmental Toxicology
Sammanfattning : General toxicity evaluation and risk assessment for human exposure is essential when developing new pharmaceuticals and chemicals. Developmental toxicology is an important part of this risk assessment which consumes large resources and many laboratory animals. LÄS MER
5. Characterization of human dopaminergic neurons in the developing mesencephalon and upon differentiation of stem cells- for replacement therapy in Parkinson´s disease
Sammanfattning : Cell-replacement therapy is a promising approach for treating patients with Parkinson ́s disease (PD). For this purpose, there is a need for developing a protocol that can generate high numbers of human transplantable mesencephalic dopaminer- gic (mesDA) neurons. LÄS MER
