WB-F344 Cells

The WB-F344 rat liver epithelial cell line is a non-tumorigenic line extensively used in studies focusing on liver physiology, toxicology, and carcinogenesis. Originating from normal adult rat liver, these cells were initially derived to facilitate investigations into the mechanisms of liver regeneration and the bioactivation of chemical carcinogens in vitro. They are diploid, exhibiting stable karyotypic features that are characteristic of normal rat liver cells, making them a valuable model for genetic and cytological studies.

WB-F344 cells are particularly noted for their ability to differentiate into bile duct-like structures in response to certain stimuli, which makes them an excellent tool for studying biliary epithelial function and pathology. Their robust response to growth factors and their ability to undergo oncogenic transformation under specific experimental conditions also provide a platform for exploring the molecular pathways involved in liver disease and cancer. Furthermore, these cells have been employed in studies assessing the hepatic toxicity of environmental and pharmaceutical compounds, providing critical insights into hepatocyte response to xenobiotic exposure.

Due to their well-characterized nature and versatility in research applications, WB-F344 cells serve as a foundational model in hepatological research. Their use has contributed significantly to our understanding of liver biology, particularly in areas related to cell differentiation, carcinogenesis, and the hepatic response to injury and chemical insults.
