Understanding these interactions has remained essential for developing effective therapies, yet models capable of capturing the full complexity of motor neuron disease pathology remained limited. Induced pluripotent stem cell-derived 3D models have emerged as a means of addressing this gap, enabling researchers to study distinct aspects of disease biology in a physiologically relevant context.<\/p>\n<h2><strong>Spinal Cord, Muscle, and Neuromuscular Organoid Models<\/strong><\/h2>\n<p>The authors described a range of induced pluripotent stem cell-derived 3D models developed to capture distinct aspects of motor neuron disease pathology. Spinal cord organoids were used to investigate cell-autonomous mechanisms and motor neuron-glia interactions, with axially elongated spinal cord organoids applied specifically to study developmental vulnerability. Three-dimensional muscle and combined neuromuscular models were used to dissect muscle pathology and neuromuscular junction dismantling. The authors also reviewed advances in bioengineering, machine learning, and human trunk-like models, which together began to reproduce the coordinated development of the multiple tissues affected in motor neuron diseases.<\/p>\n<h2><strong>Insights into Disease Mechanisms and Drug Repurposing<\/strong><\/h2>\n<p>These systems have advanced understanding of motor neuron disease mechanisms and highlighted opportunities for drug repurposing. Spinal cord organoid models revealed motor neuron-glia interactions relevant to disease progression, while neuromuscular models captured neuromuscular junction breakdown associated with motor neuron loss. Combined bioengineering and machine learning approaches allowed researchers to model the coordinated development of multiple affected tissue types, moving towards more integrated disease modelling. As this was a review rather than a primary experimental study, no sample sizes, outcome measures, or statistical comparisons were reported.<\/p>\n<h2><strong>A Framework for Future 3D Model Selection<\/strong><\/h2>\n<p>The authors have proposed a mechanism-informed and phenotype-informed framework to guide selection of 3D models for future motor neuron disease research and to help prioritise promising avenues for therapeutic development. As 3D organoid and neuromuscular models continue to evolve, they are likely to play an increasingly important role in dissecting the mechanisms underlying motor neuron diseases and in accelerating translation towards new therapies.<\/p>\n<h2><strong>Reference<\/strong><\/h2>\n<p>Frizzi B et al.
