The liver is an important organ in vertebrates that plays an essential role in metabolism. It is also responsible for storing and redistributing nutrients such as carbohydrates, fats, and vitamins in the body. Additionally, the liver releases bile salts which are critical for digesting food and eliminating toxic metabolites from the body. Cells of Liver The liver comprises four major types of cells— hepatocytes, stellate, Kupffer, and sinusoidal endothelial cells. The hepatocytes are large...

To help assess the molecular mechanisms underlying zebrafish biliary-driven liver regeneration, we established a liver injury model in which the nitroreductase-expressing hepatocytes are genetically ablated upon metronidazole treatment. In this protocol, we describe how to adeptly manipulate, monitor and analyze hepatocyte ablation and biliary-driven liver regeneration.

Sustained fibrosis with deposition of excessive extracellular matrix proteins leads to cirrhosis. Alcohol abuse is one of the main causes of severe liver disease. We established an ethanol-induced zebrafish fibrotic liver model to study the mechanisms and strategies of promoting hepatocyte regeneration upon alcohol-induced injury.

Liver diseases are induced by many causes that promote fibrosis or cirrhosis. Transplantation is the only option for recovering health. However, given the scarcity of transplantable organs, alternatives must be explored. Our research proposes the implantation of collagen scaffolds in liver tissue from an animal model.

Here, we present a new method for partial resection of the left hepatic lobe in neonatal (day 0) mice. This new protocol is suitable for studying acute liver injury and injury response in the neonatal setting.
FAQs
Liver regeneration depends on coordinated signaling rather than hepatocyte division alone. Inflammatory cells, the extracellular matrix, and growth factors provide signals that regulate both proliferation and tissue remodeling. This coordination matters because restoring cell number without reorganizing the surrounding tissue would not address the broader repair response needed to support recovered liver structure and function.
Mature hepatocytes serve as the principal dividing cells described in this regenerative response. After injury or partial removal, they can re-enter the cell cycle and produce new cells. Their ability to proliferate allows the liver to rebuild tissue while supporting the return of essential metabolic, detoxification, and synthetic activities.
Extracellular matrix remodeling provides part of the tissue context in which liver cells proliferate and repair occurs. It works alongside inflammatory signals and growth factors rather than acting as an isolated process. This coordinated remodeling helps connect cellular expansion with restoration of organized tissue, making it important for recovery of liver structure and function.
Effective regeneration supports recovery of several functions at once, including metabolism, detoxification, and synthesis. The importance of this response therefore extends beyond replacing lost tissue mass. By helping restore both tissue and activity after damage, regeneration contributes to the liver’s ability to resume its broad biological roles.
The liver provides a useful biological model because its response to injury or partial removal links mature-cell proliferation with signals from inflammatory cells, extracellular matrix, and growth factors. Researchers can therefore examine how tissue loss triggers coordinated repair. Findings from this system help clarify general principles of organ recovery and remodeling.
Research on liver regeneration can reveal how repair responses support or fail to restore liver tissue and function. This makes the process relevant to chronic liver disease, where understanding tissue repair is important. The same biological framework helps researchers investigate how regenerative capacity might relate to ongoing injury and impaired recovery.
Liver regeneration research provides biological context for developing strategies that promote organ repair. It also informs transplantation research by highlighting how hepatocyte proliferation, inflammatory signals, extracellular matrix, and growth factors contribute to recovery. These insights may help guide approaches intended to restore liver mass and function after tissue loss or injury.
