Eight transformed clones (SVFN1-8) were isolated from the soft-agar plates and grown into individual cell lines and their genomic DNA extracted for genome-wide SNP array profiling (Fig. 5A) to obtain genomic instability in the form of loss of heterozygosity (LOH) and copy number abnormality (CNA).

DNA copy number abnormality was assessed by a molecular inversion probe (MIP) platform with focal amplification and high resolution (~10 K bp) as previously described [ 24– 26].
