Chronic Rejection Grading

In this image, a cytokeratin stain is being used to highlight a rare "biliary epithelial cell" or ductal remnant remaining at the edge of the triad in a liver with complete bile duct loss from chronic rejection. It is possible, but not proven, that recovery from chronic rejection may be a result of ductal repair by progenitor cells in the periportal region or canals of Herring.
