ALS Stem Cell Model Reveals Increased Susceptibility to Cell Death

Amyotrophic lateral sclerosis (ALS) is a fast-progressing neurodegenerative disease with an average survival time of three years. In ALS, certain types of neurons called motor neurons that are required for muscle contractions die off, leading to progressive paralysis affecting most muscles of the body. The molecular causes of ALS are poorly understood, and effective treatments are missing.
