Ideogram of gains and losses according to the genomewide array CGH in 12 FCL-derived cell lines.

Lines on the right of each ideogram indicate genomic gains, lines on the left show losses of chromosomal material, and high-level amplifications are symbolized by bold lines. Cell lines are indicated by numbers above each line and correspond to Karpas 231 (no. 1); OZ (no. 2); OCI-LY8 (no. 3); DOHH2 (no. 4); SUDHL6 (no. 5); PR1 (no. 6); Karpas 422 (no. 7); BEVA (no. 8); VAL (no. 9); Karpas 353 (no. 10); ROS50 (no. 11); and RL (no. 12). Black circles localize the regions commonly acquired upon transformation in patients with FCL.
