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 ]
Skin tissue can be regenerated in vivo or in vitro. Other organs and body parts that have been procured to regenerate include: penis, fats, vagina, brain tissue, thymus, and a scaled down human heart. One goal of scientists is to induce full regeneration in more human organs. There are various techniques that can induce regeneration.
With the cancer in her bowels having been removed, doctors started looking at liver transplants for the liver tumour. After being added to the transplant list in February 2024, Ms Perea found a ...
A liver support system or diachysis is a type of therapeutic device to assist in performing the functions of the liver. Such systems focus either on removing the accumulating toxins (liver dialysis), or providing additional replacement of the metabolic functions of the liver through the inclusion of hepatocytes to the device (bioartificial liver device).
Liver transplantation is a potential treatment for acute or chronic conditions which cause irreversible and severe ("end-stage") liver dysfunction. [4] Since the procedure carries relatively high risks, is resource-intensive, and requires major life modifications after surgery, it is reserved for dire circumstances.
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]
The activated stellate cell as a myofibroblast is also responsible for secreting components of the extracellular matrix including collagen that can promote the development of fibrosis and the formation of scar tissue. Continued fibrosis is thought to be responsible for the development of cirrhosis and liver cancer. [10] [11]
The artificial liver is designed to serve as a supportive device, either allowing the liver to regenerate upon failure, or to bridge the patient's liver functions until transplant is available. [28] It is only made possible by the fact that it uses real liver cells (hepatocytes), and even then, it is not a permanent substitute.
