Figure 2From: Copy number gain of MYCN gene is a recurrent genetic aberration and favorable prognostic factor in Chinese pediatric neuroblastoma patientsRepresentative FISH image of neuroblastic tumor cells displaying MYCN gene status. A: Amplification:The number of MYCN signals (green) is more than 10 copies of the CEP2 probe signals (red). B: Gain:The number of MYCN signals (green) is 1 copy greater than the CEP2 probe signals; C: No Alteration: Cells with MYCN signals (green) showing the same numbers of the CEP2 probe signals.
