Does TopIIbeta function cell-autonomously in neurons or require non-neuronal cell interactions for neurite outgrowth?

While the study shows TopIIbeta knockout neurons have shorter neurites in culture and fail to form neuromuscular contacts, it’s unclear whether this reflects intrinsic neuronal defects or disrupted cell-cell signaling. This distinction is crucial for understanding neuromuscular junction formation disorders.
