Abstract: Neuromuscular networks assemble during early human embryonic development and are essentialfor the control of body movement. Previous neuromuscular junction modeling effortsusing human pluripotent stem cells (hPSCs) generated either spinal cord neurons orskeletal muscles in monolayer culture. Here, we use hPSC-derived axial stem cells,the building blocks of the posterior body, to simultaneously generate spinal cordneurons and skeletal muscle cells that self-organize to generate human neuromuscularorganoids (NMOs) that can be maintained in 3D for several months. Single-cell RNA-sequencingof individual organoids revealed reproducibility across experiments and enabled the tracking of the neural and mesodermal differentiation trajectories as organoids developedand matured. NMOs contain functional neuromuscular junctions supported by terminalSchwann cells. They contract and develop central pattern generator-like neuronal circuits.Finally, we successfully use NMOs to recapitulate key aspects of myasthenia gravispathology, thus highlighting the significant potential of NMOs for modeling neuromuscular diseases in the future.
