Localized detection of HPV was performed on laser-capture micro-dissected (LCM) regions from the hematoxylin and eosin (H&E) before section.
aHistological images of micro-dissected regions 1AI, 1AII, 1AIII, 1BI, 1BII, 1CV and 1CVI are shown in Figure 3.
bThese regions were micro-dissected from the hematoxylin and eosin (H&E) after section instead of the H&E before section.
cRegion 1CV was micro-dissected from the p16 section. This region corresponds with region 1CI, that was micro-dissected from the H&E before section.
dRegion 1CVI was micro-dissected from the p16 section. This region corresponds with region 1CIII, that was micro-dissected from the H&E before section.
eHistological diagnosis was CIN3 in the H&E before section and CIN2 in the H&E after section
