Stem cells may divide indefinitely in vitro and give rise to a wide range of specialized cells. They have the potential to grow into blood, neurons, bone, muscle, skin, and other cell types. They have been recognized as a crucial resource in the investigation of the origins of ALS and the development of novel therapies.
Stem cells could ultimately play a key role in ALS treatment. The most logical use would be to distribute growth factors or neuroprotective chemicals to motor neurons in the spinal cord using stem cells or cells produced from them. These stem cell transplants are still in the early phases of clinical studies, but they tend to be safe.
