Fig 1. VEGFA copy number status in colorectal cancers measured by fluorescent in situ hybridization.

Representative micrographs of (A) diploid, (B) polysomic and (C) amplified VEGFA using fluorescent in situ hybridization (FISH). FISH analysis was performed using two-color probes for VEGFA (red) and internal control (green). Scale bar 20 μm.
