Neuroblastoma is the most common solid extra-cranial tumor in children, with an enigmatic origin that precludes the development of relapse-free treatments. These tumors often form in the adrenal gland region and are composed of sympathetic neuronal precursors staled in their development. We focused on unravelling the development of cells building the adrenal gland with a single-cell transcriptomic approach to reveal the secret of neuroblastoma. We found a large human-specific population of sympathetic neuronal precursors which reside inside the adrenal medulla. Moreover, we proved that these sympathetic precursors unlike other sympathetic neurons in human originate from nerve-associated multipotent glial cells and their intermediate developmental states correspond to malignant cells from neuroblastoma. Altogether, we found the potential cellular source of neuroblastoma with a unique embryonic developmental pathway, which can be targeted during treatment.
