Gene set enrichment analysis showed that CD133− cells present an adrenergic phenotype associated with high levels of PHOX2A, PHOX2B, and DBH, typical of classic NB cells, while the CD133+ cells showed high levels of SNAI2, VIM (vimentin), and FN1 (fibronectin), which are typical mesenchymal cell markers (63). Here, VIM is linked to neuroblastoma.
