What is liver regeneration?
liver regeneration is a phenomenon that the liver can again grow their own tissues to repair from damage or surgical removal of up to two thirds of their own tissue. Research seems to indicate that when up to two -thirds of the patient's liver is removed, liver regeneration can cause the liver to return to its normal size within a week. Dog research has shown that small liver transplanted into large dogs can grow until they reach the appropriate size, while the large liver into small dogs usually shrink until they reach the appropriate size. Similar examples of liver growth or shrinkage have been observed in human patients who received liver transplants. Scientists are still investigating the mechanics of liver regeneration, but they believe that liver cells have an almost infinite ability to regenerate. Examples of complete regeneration of the liver partial heptectomy or surgical removal of part of the liver is many. Experts believe that more cases of liver regeneration in the same patient are possible. Scientists workingThe era observed up to a dozen cases of liver regeneration in the same test entity.
The process of tissue regeneration in the liver usually starts about 10 to 12 hours after damage, and on average it takes three days to fully regenerate the liver. When part of the liver is damaged or removed, the liver cells that remain, begin to secrete a substance known as the growth factor of hepatocytes. Hepatocyte growth factor stimulates hepatocytes or liver cells to start reproducing. Other growth factors and hormones are usually involved, helping to stimulate the production of new biliary epithelial cells and new endothelial cells in the liver. Experts of the confident is not limited to the number of times can copy one hepatocyte.
experts once believed that the liver was regenerated by the production of special cells with embryonic or fetal characteristics. However, recent research suggests that the liver regenerates the mediumCity of common cell replication. Although she regenerates herself, the liver generally still fulfills its basic functions in the body. These basic functions include blood and tissue detoxification, regulation of metabolism and regulation of fluid levels throughout the body.
