Frequent EGFR Positivity and Overexpression in High-Grade Areas of Human MPNSTs
Figure 4
CISH and FISH analysis on the R84 MPNST sample. (a) The mean number of spot detected in the nuclei of 40 to 60 tumour cells in this sample stained by CISH was 3.3. (b) FISH confirmed multiple spot of EGFR (red) but revealed a polysomy of chromosome 7 (green) for this tumour. Scale bar represents 5 μm.
