MYCN and neuroblastoma: To investigate the cellular and molecular mechanisms underlying the fate determination of neuroblastoma cells in Th-MYCN+/− mice, we performed scRNA-seq of SMG tissues from 3-week-old wild-type (WT, n = 1), 3-week-old Th-MYCN+/− (n = 10), and 6-week-old Th-MYCN+/− mice (n = 1) (Figure 1D).
