Portal fibroblasts are an important yet often overlooked non-parenchymal cell population in the liver. They are distinct from hepatic stellate cells, yet like stellate cells differentiate in the setting of chronic injury to fibrogenic myofibroblasts, playing an important role in collagen production in the fibrotic liver. Portal fibroblasts are located adjacent to bile duct epithelia and thus play a particularly significant role in biliary fibrosis. New data suggest that they may also have key functions independent of fibrogenesis. This review will address the definition and characteristics of PF as well as their signaling pathways, interactions with the biliary epithelium, and contributions to liver pathobiology. We conclude that portal fibroblasts are an important and multifunctional non-parenchymal cell population in need of further study.
