Models of Liver Injury, Cirrhosis, Failure

Greentech provides a broad spectrum of animal models of liver diseases for drug efficacy testing including animal models of acute hepatic damage, animal models of liver cirrhosis, and animal models of liver failure. We have extensive experience in preclinical pharmacology studies, especially metabolic diseases, and are capable of customizing animal models according to clients’ needs.

Our Animal Models of Liver Damage, Cirrhosis, Failure

Clinical Assessment

(1) Body weight, liver index, food intake

(2) Liver function: ALT, AST, ALB, LDH, etc.

(3) Lipid metabolism: TC, HDL, LDL, TG, etc.

(4) Cholestasis: T-BIL, D-BIL, I-BIL

(5) Biliary obstruction: ALP, GGT

(6) Hepatic histopathology: HE, MASSON staining

(7) Hepatic fibrosis: detection of collagen and hydroxyproline

(8) Imaging: color ultrasound, CT, PET/CT, etc.

Case Study

Figure 2. Hepatic histopathology (HE/SR staining, immunohistochemical staining of α-SMA) 2 weeks after bile duct ligation in SD rats.

2. ANIT induced rat PBC models
