mIHC showing the glands, goblet cells and surfaces of three different polyp subtypes. The epithelial cells were stained with EpCAM antibody (yellow), and the cell nuclei were stained with DAPI (blue). (a) Representative mIHC images of glands across three different polyp subtypes. Scale bar, 100 μm. (b) Representative enlarged mIHC images of goblet cells (red arrow) across three different polyp subtypes. Scale bar, 100 μm. (c) Representative mIHC images of the surfaces of three different polyp subtypes. The red arrow indicates surface erosion. Scale bar, 100 μm
