The liver is an essential hub for material and energy metabolic processes. The impact of alcohol, drugs, and toxic chemicals usually produces acute or chronic liver injury, which can progress to liver fibrosis, cirrhosis, or liver cancer if not appropriately managed. Consequently, experimental animal models of liver disease are essential for investigating the pathophysiology of liver disease and screening therapeutic medicines.GemPharmatech offers liver fibrosis models, metabolic dysfunction-associated steatohepatitis models, and related-efficacy evaluation services.
