Fig. 1From: MYCN amplification predicts poor prognosis based on interphase fluorescence in situ hybridization analysis of bone marrow cells in bone marrow metastases of neuroblastomaRepresentative FISH images of BM cells. a The status of MYCN amplification using a dual-color probe. Green signals represent the specific probe for MYCN and red signals stand for centromeric chromosome 2 probes. MYCN signals show more than 30 copies within the nuclei. b The status of 1pLOH using a dual-color probe. Green signals represent the copy numbers at 1q21 and red signals are the specific DNA probe of 1p36. Bars 5 μmBack to article page
