3. FIGURE 2
Four tumors samples exhibiting different ALK break-apart FISH signal patterns. A, ALK negative polysomic nuclei showing between five and nine fused signals per cell. B, ALK negative amplification nuclei (arrow) showing clusters of fused signals. C, ALK positive nuclei showing split signals (arrows) and fused signal gains. D, ALK positive nuclei showing isolated single red signals (arrows).
