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]
Up to 40% of full thickness skin can be removed without scarring in an area, in a fractional pattern via coring of tissue. [1] Some human organs and tissues regenerate rather than simply scar, as a result of injury. These include the liver, fingertips, and endometrium.
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. [16] (Figure 2) Figure 2: Mechanism of liver regeneration in adult humans
This can result in impotence, infertility, loss of sexual drive, and testicular atrophy. A swollen scrotum may also be evident. [34] Liver size can be enlarged, normal, or shrunken in people with cirrhosis. [35] As the disease progresses, the liver will typically shrink due to the result of scarring. [36] Jaundice is the yellowing of the skin.
Phagocytosis of dead tissue can consequently activate the signaling cascade necessary for regeneration. For instance, the macrophages phagocytosis in liver of dead or necrotic hepatocytes induces Wnt expression, which can influence the proliferation and differentiation of hepatic progenitor cells into liver cells.

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.
