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 ]
The liver is the only human internal organ capable of natural regeneration of lost tissue; as little as 25% of a liver can regenerate into a whole liver. [75] This is, however, not true regeneration but rather compensatory growth in mammals. [76]
This is in contrast to wound healing, or partial regeneration, which involves closing up the injury site with some gradation of scar tissue. Some tissues such as skin, the vas deferens, and large organs including the liver can regrow quite readily, while others have been thought to have little or no capacity for regeneration following an injury.
Spontaneous regeneration occurs in the human body naturally. The most recognised example of this is the regeneration of the liver, [16] which can regenerate up to two thirds of its mass when injured by surgical removal, ischaemia or after exposure to harmful toxins.

Michalopoulos has contributed to the field of pathology through his work on liver function, regeneration, and carcinogenesis.He has utilized various experimental models, such as hepatocyte cultures, hepatic organoids, established cell lines, studies on liver regeneration after partial hepatectomy, examinations of regeneration through progenitor cell pathways, investigations into liver ...
This hematopoietic function is not normally seen after birth; however, in certain pathological conditions this function may still be seen. It is important to note that the liver is an essential organ and it is the only one in the body that has the ability to regenerate itself after surgery or damage. [4]
How Long Will It Take Topiramate to Work? There’s no set time frame for topiramate to start working for weight loss, as it’s not designed to be a weight loss medication.Research shows some ...
The function and role of quiescent hepatic stellate cells is unclear. Recent evidence suggests a role as a liver-resident antigen-presenting cell, presenting lipid antigens to and stimulating proliferation of NKT cells. [7] When the liver is damaged, stellate cells can change into an activated state.
