Metabolic dysfunction–associated steatotic liver disease (MASLD) is the most prevalent hepatic pathology worldwide, with significant potential for progression to cirrhosis and ultimately end-stage liver disease. Accordingly, a wide range of preclinical models have been developed to better understand the disease mechanisms and progression as well as to accelerate drug discovery. These include in vitro, ex vivo, and in vivo models, which offer unique advantages yet differ in terms of disease driver, species used, and biological complexity—ranging from benchtop cellular systems to whole organs and organisms. In this review, we provide a comprehensive overview of the technologies currently used for the study of MASLD, with a focus on how standardization of disease progression across models may aid therapeutic development.
