Microarray analysis of bone marrow tissue from neuroblastoma patients

Microarray gene expression profiling of bone marrow tissue obtained from neuroblastoma patients. Bone marrow cells were isolated as GD2 negative cell fraction by immunomagnetic beads from localised, stage 1-3 neuroblastoma patients (n=23), metastatic stage 4 neuroblastoma patients (n=9) and healthy donors (n=8).
