Objectif State of problem: Grafting of primary embryonic neural tissue has proven that cell replacement therapy is a viable approach to the treatment of PD. However, the number of successfully grafted patients is relatively small due to limited access to suitable donor tissue.Alternative sources of donor tissue - which are reproducibly homogeneous in their cellular composition and can be generated in large quantities - are urgently needed for cell transplantation to become a widely available therapy for PD.Overriding objective: To propagate human embryonic stem (hES) cell lines and differentiate them into dopaminergic (DA-ergic) neurons, which can be used for neural grafting in Parkinson's disease (PD).Aims of the present project:- To expand cells from hES cell lines established by Lund University collaborators (SAO1 (Cell Therapeutic Scandinavia AB, Goteborg, Sweden) and #237 (Karolinska Institute, Stockholm, Sweden)) and to identify epigenetic stimuli that promote their differentiation into a uniform, enriched population of DA-ergic neurons.- To assess the DA-ergic phenotype of the hES-cell-derived neurons in vitro, regarding the expression of markers for dopamine production and handling, and exhibition of spontaneous firing as well as spontaneous and drug-induced dopamine release.- To assess the ability of grafted hES-cell derived neurons to restore DA-ergic neurotransmission in vivo by examining their effects on behaviour in immunosuppressed hemiparkinsonian rats and their capacity to produce and release dopamine, as well as to form synapses.
