The lack of pertinent models for neuromuscular disorders has rendered many important questions in disease pathogenesis inaccessible. Current drugs provide only limited benefit by alleviating certain symptoms. Clearly, the development of efficacious preventive or protective therapies is impeded by our limited knowledge of the neurobiology of these severe conditions and the lack of more faithful assay systems.
Human embryonic stem cells derived from affected embryos during a pre-implantation diagnostic (PGD), as well as the conversion of somatic cells, such as skin fibroblasts, into induced pluripotent stem cells by genetic manipulation, offer the unique opportunity to have access to a large spectrum of disease-specific cell models.
This project aims to the elaboration of new therapeutic strategies for neuromuscular diseases. Indeed, human pluripotent stem cell lines and derivatives, which express a disease-related mutated gene, represent a relevant and pertinent disease cell model to analyse pathological mechanisms through large-scale drug screenings. Consequently we highlight and investigate new therapeutic strategies.
Validating this original concept, we previously demonstrated that PGD-derived hES cells and their derivatives, which express the causal mutation implicated in the Myotonic Dystrophy type 1 (DM1), offer pertinent disease-cell models, applicable for a wide systemic mechanistic analysis ranging from functional studies at the cellular level to a large-scale drug screening. Our goal is, through the greater understanding of pathological mechanisms implicated in this disease, to identify new therapeutic strategies for this neuromuscular disease and to extend this experimental approach to other neuromuscular diseases.
