IMP3 and p53 signatures in tubal epithelia from a high-risk patient. Photographs illustrated examples of normal-looking epithelia in fimbria with strong immunoreactivity for IMP3 and p53 (40x). A closer view of the IMP3 and p53 signatures was shown in inserts (200x) of the panel. Immunoreactivity for IMP3 and p53 were identified in 2 different sites indicated by red arrows in the same fallopian tube. Apparently, the majority of the IMP3 and p53 signatures were overlapped in this particular stretch of the tubal epithelia.
