We describe a method to produce an animal model of liver fibrosis in the rat, and assess the degree of fibrosis by histological examination of the liver. The model can be used to study the development of liver disease as well as to test the efficacy of potential anti-fibrotic agents.

Mouse model of metabolic dysfunction-associated steatotic liver disease (MASLD) with metabolic dysfunction, hepatic gene expression changes, and liver histopathological alterations that resemble human MASLD, including fibrosis that progresses to advanced fibrosis stage 3. This model can be used in studies of MASLD pathophysiology and in pre-clinical studies of new therapies.

Disruption of bile flow results in severe inflammatory cholestatic liver injury with a characteristic time-dependent sequence of morphological alterations. Here we present a protocol for the surgical ligation of the common bile duct in mice that allows to induce a strong fibrotic response after 21 to 28 days.

The study of liver sinusoidal endothelial cells (SECs) must be performed with primary cells obtained from the animal as no cell lines exist. This method relies on liver digestion and differential centrifugation for SEC purification for subsequent culturing and experimentation.
FAQs
Persistent liver injury activates hepatic stellate cells, causing them to transform into collagen-producing, myofibroblast-like cells. These altered cells then contribute to extracellular matrix deposition, changing the tissue environment rather than merely reflecting existing damage. Tracking this cellular transition helps biologists connect repeated injury with the structural remodeling that characterizes advancing fibrosis.
The balance between matrix deposition and matrix degradation influences whether scarring stabilizes or continues to expand. Ongoing inflammation can favor continued accumulation, while impaired degradation reduces removal of extracellular matrix proteins. This imbalance matters because it links inflammatory activity to progressive architectural disruption and helps identify biological points at which disease progression might be limited.
Although the initiating insults differ, chronic viral infection, alcohol-associated liver disease, metabolic dysfunction, and other injuries can repeatedly stimulate the liver’s biological response to damage. Their shared relevance is persistence: recurrent injury maintains stellate-cell activation, matrix deposition, and inflammatory activity. Comparing these contexts helps researchers distinguish cause-specific factors from common mechanisms of fibrotic progression.
Studies of liver fibrosis commonly connect three levels of evidence: the state of hepatic stellate cells, the amount and handling of extracellular matrix proteins, and the presence of ongoing inflammation. Examining these together is more informative than considering scar accumulation alone because it relates cellular activity to tissue remodeling, disease progression, and potential intervention points.
Investigating Liver Fibrosis can support biomarker development by revealing measurable features associated with cellular activation, matrix accumulation, inflammation, or impaired degradation. Diagnostic methods built around such features may help characterize fibrotic change and support disease evaluation. The biological goal is to translate mechanisms observed in the liver into information useful for diagnosis.
The biological importance of progression lies in its potential consequences: advanced scarring can develop into cirrhosis and liver failure. Research therefore prioritizes treatments that prevent further progression or promote reversal, rather than focusing only on the presence of scar tissue. Mechanistic studies help identify how cellular and matrix changes might be altered to protect liver structure and function.
