Popis: There is evidence for the involvement of human skeletal muscle (hSKM) in ALS neuromuscular junction (NMJ) dysfunction. However, the specific avenue by which the hSKM contributes to NMJ disruption is not well understood due to limited human-based studies performed to investigate the subject. Thus, hSKM and human motoneurons (hMN) generated from induced pluripotent stem cells of healthy individuals (WT) and ALS patients with two different SOD1 mutations were integrated into functional NMJ systems to investigate and compare the pathological contribution of the hSKM and hMN to ALS NMJ disruption. Morphological assessment of ALS NMJs demonstrated reduced acetylcholine receptor clustering in the post-synaptic membrane of co-cultures with ALS hSKM (hSKM
