Ischemic hepatitis, also known as shock liver, is a condition defined as an acute liver injury caused by insufficient blood flow (and consequently insufficient oxygen delivery) to the liver. [5]
Liver diseases, including conditions such as non-alcoholic fatty liver disease (NAFLD), alcohol-related liver disease (ALD), and viral hepatitis, are significant public health concerns worldwide. In the United States, NAFLD is the most common chronic liver condition, affecting approximately 24% of the population, with the prevalence rising due ...
The liver plays a vital role in many metabolic processes in the body including protein synthesis, detoxification, nutrient storage (such as glycogen), platelet production and clearance of bilirubin. With progressive liver damage; hepatocyte death and replacement of functional liver tissue with fibrosis in cirrhosis, these processes are disrupted.
Ballooning degeneration – hepatocytes in the setting of alcoholic change often swell up with excess fat, water and protein; normally these proteins are exported into the bloodstream. Accompanied with ballooning, there is necrotic damage. The swelling is capable of blocking nearby biliary ducts, leading to diffuse cholestasis. [6]
Cirrhosis is a late stage of serious liver disease marked by inflammation (swelling), fibrosis (cellular hardening) and damaged membranes preventing detoxification of chemicals in the body, ending in scarring and necrosis (cell death). [11] Between 10% and 20% of heavy drinkers will develop cirrhosis of the liver (NIAAA, 1993).
Hepatotoxicity and drug-induced liver injury also account for a substantial number of compound failures, highlighting the need for toxicity prediction models (e.g. DTI), [2] and drug screening assays, such as stem cell-derived hepatocyte-like cells, that are capable of detecting toxicity early in the drug development process.

The typical hepatocyte is cubical with sides of 20-30 μm, (in comparison, a human hair has a diameter of 17 to 180 μm). [1] The typical volume of a hepatocyte is 3.4 x 10 −9 cm 3 . [ 2 ] Smooth endoplasmic reticulum is abundant in hepatocytes, in contrast to most other cell types.
Liver regeneration is the process by which the liver is able to replace damaged or lost liver tissue. The liver is the only visceral organ with the capacity to regenerate. [1] [2] The liver can regenerate after partial hepatectomy or injury due to hepatotoxic agents such as certain medications, toxins, or chemicals. [3]
