Ultrastructural characteristics of novel epithelial cell types identified in human pathologic liver specimens with chronic ductular reaction.


Previous immunohistochemical studies on human liver biopsies with chronic ductular reaction revealed the presence of "small cells" with bile-duct type cytokeratin profile in the periportal area. This study identified similar cells by electron microscopy. The authors studied 13 human liver specimens with various liver diseases, but all characterized by… (More)
