Fig. (6) Genomic imbalances using 4x44K oligo array CGH methods. Array CGH analysis revealed that the established cell lines (GDLB-GCB1 and GDLB-GCB2) showed the identical genomic imbalances as the original samples (UPN1 and 2), indicating that the established cell lines and original samples were derived from the identical clones. Abbreviation: CGH, comparative genomic hybridization; UPN, unique patient number.
