What is Liver Regeneration
The liver is the largest gland in the human body and is a unique organ. The liver performs various important functions in the human body like removing waste or toxins from the body, controlling blood sugar, converting glucose into energy, balancing protein nutrition intake, metabolizing hormones, etc. Generally, the primary function of the liver is to filter waste or toxins, so the risk of the liver becoming infected or injured is also high. Liver transplant doctors in india associated with our team say that our liver has regenerative properties that can repair or regenerate itself after partial hepatectomy due to underlying damage, injury, hepatotoxic agents like drugs, toxins, chemicals, or infections. This process is called liver regeneration in medical language. According to liver transplant specialist, liver regeneration is a complex process, which is explained in current hepatology research based on which liver surgeons are providing new pace and direction to liver transplant surgery at the best liver transplant hospital in India. According to them, the liver heals its damage in 15 to 20 days and generally age has no effect on liver regeneration, and a liver completely regenerates in an average of three years, which means that your liver will never age under normal conditions. In this blog, our team provides you with a research review of promising advances in liver regeneration research.
Natural Regenerative Capacity
The liver transplant expert says the liver’s natural regenerative capacity to replace lost tissue and restore its full size and function after injury or liver transplant surgery is unmatched. Unlike most organs in your body, the liver can regenerate itself by up to 70%. Current medical understanding of natural regenerative capacity has advanced significantly since the initial descriptions of hepatectomy research in India which guides the enormous potential of liver transplant treatment. Nevertheless, there remains a need for more important discoveries regarding the biologically and medically important processes of natural regenerative capacity. The best liver transplant specialist associated with our team explain the natural regenerative capacity of the liver in which dormant liver cells (hepatocytes) are induced to re-enter the cell cycle and existing hepatocytes are stimulated to proliferate actively. This process of liver regeneration involves a highly organized tissue remodeling process. In this overall process, liver cytokines help stimulate hepatocytes to become sensitive to growth factors resulting in regrowth of hepatocytes. This entire process reflects interactions between hepatocytes, cytokines, and certain other signaling molecules to maintain normal liver mass and function, making the natural regenerative capacity a unique and important part of maintaining the overall health and metabolic balance of the liver.
Molecular Mechanisms
Liver regeneration is driven by a complex interplay of molecular mechanisms. Generally, immediate early genes after partial hepatectomy are induced by growth factors resulting in a specific biological process including DNA synthesis, cell replication, and an increase in cell size involving multiple signaling pathways, growth factors, and cytokines. According to the Liver regeneration research and liver transplant specialist, these immediate early genes in liver regeneration are a process driven by the immune system and cytokine release that occurs in hepatocytes as well as non-parenchymal liver cells, with hepatocytes replicating earlier than other cell types. In this process, DNA synthesis proceeds as an organized chain among hepatocytes, starting with hepatocytes near the portal vein and progressing to cells adjacent to the central vein. Our team covered these factors in a review of new and important signaling molecules involved in liver regeneration research.
- Hepatocyte Growth Factor (HGF): Promotes hepatocyte proliferation and survival.
- Transforming growth factor-alpha (TGF-α): Stimulates cell division and differentiation.
- Epidermal growth factor (EGF): Enhances cell growth and regeneration.
- Cytokines (e.g., IL-6, TNF-α): Play a role in initiating and modulating the regenerative response.
- Wnt/β-catenin signaling pathway: Critical for liver cell proliferation and differentiation.
The complex coordination of these molecules ensures that your liver’s regenerative capacity is efficient and effective. This process can progress liver regeneration with restoration of liver structure and function, providing potential therapeutic avenues for liver transplant surgery. Our team believes that understanding promising treatments for liver regeneration will lead to promising therapeutic strategies.
