Liver regeneration is the process by which the liver can repair and regrow itself after injury or partial removal. The liver is unique among organs because it can regenerate to its original size and function, even if up to 70% of it is removed. This ability is crucial for maintaining overall health, as the liver performs essential functions like detoxification, metabolism, and protein synthesis. The regeneration process involves the proliferation of liver cells, known as hepatocytes, which respond to signals from the body to initiate growth. Factors such as growth factors and cytokines play a significant role in regulating this process. Liver regeneration is vital for recovery from surgeries, injuries, or diseases affecting liver function.
