Neuroblastoma Metastases: Leveraging the Avian Neural Crest.

Neuroblastoma, an embryonal cancer of neural crest origin, shows metastases frequently at diagnosis. In this issue of Cancer Cell, Delloye-Bourgeois and colleagues demonstrate that neuroblastoma cell lines and patient-derived xenografts engraft and adopt a metastatic program in chick embryos. They identify Sema3C as a candidate switch that regulates metastatic spread.
