ALS disrupts spinal motor neuron maturation and aging pathways within gene co-expression networks

ALS patient iPSC-derived motor neurons aim to model disease phenotypes. The authors demonstrate that these cells transcriptomically resemble fetal rather than adult spinal motor neurons, and familial and sporadic forms of ALS disrupt gene networks and pathways associated with neuronal maturation and aging. These data provide a resource for further understanding how molecular changes in motor neurons lead to disease.
