To develop protocols for production of transplantable mesDA and striatal GABAergic progenitors from human ES and NS cell lines, building on recent developments in stem cell biology;

To carry out pre-clinical testing of stem cell-derived mesDA and striatal GABAergic progenitors in rodent models of PD and HD with the goal to generate efficient and safe candidate cells for clinical use;

To identify procedures and safety systems that will allow complete elimination of proliferative and/or tumour-forming cells from the graft cell preparations;

To apply in vivo imaging tools for non-invasive monitoring of the survival and growth of the grafted cells, as well as tools to reveal adverse immune/inflammatory reactions to the graft;

To develop criteria, procedures and protocols for reproducible, safe and large-scale manufacture of stem cells and their progeny to clinical grade standard;

To establish a banked stock of validated, safety-qualified and traceable cells for clinical use;

To develop clinical protocols to be used in phase-I trials in patients with PD and HD;

To establish ethical and safety criteria to guide implementation of stem cell therapies in the clinic;

To develop an interface with bio-industry and devise a product-specific regulatory strategy that is compatible with a future marketing authorization;

To provide accessible information to patient organizations and lay public about the advancement in the field and future critical steps to be fulfilled;
