Neurons Derived From Embryonic Stem Cells Restore Muscle Function After Injury

Summary:

Dalhousie Medical School researchers have discovered that embryonic stem cells may play a critical role in helping people with nerve damage and motor neuron diseases, such as amyotrophic lateral sclerosis (ALS), regain muscular strength. The research team used embryonic stem cells from mice to grow motor neurons in the laboratory. They then transplanted the neurons into mouse nerves that were separated from the spinal cord. After separation, it would be expected that the nerves and muscles they control die. However, the Dalhousie group was the first in the world to find that the muscles not only were preserved by the transplantation, but they could produce about half their normal force to contract.
