Abstract/Summary

Satellite cells are dysfunctional in several neuromuscular disorders. Some muscles are more susceptible than others to disease and ageing. In vitro and in vivo model systems have shed light on many of the processes involved. in satellite cell function and dysfunction, but the drawbacks of each model system must be considered. Skeletal muscle pathology in mouse models of neuromuscular disease are affected by genetic background. A single cell approach will be useful to identify dysfunction in subsets of cell populations.
