Dear editors,Amyotrophic lateral sclerosis（ALS）is a neurodegenerative disease.It affects motor neurons in the brain and spinal cord resulting in bulbar palsy and respiratory failure.It also causes weakness of limbs.The disease usually progresses to fatal outcome within 2-4 years.Neural stem cell research for diagnosis and treatment of neurodegenerative disorders is highly promising.
