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] Only 51% of the original liver mass is required for the organ to regenerate back to full size.[2][4] The phenomenon of liver regeneration is seen in all vertebrates, from humans to fish.[5] The liver manages to restore any lost mass and adjust its size to that of the organism, while at the same time providing full support for body homeostasis during the entire regenerative process.[5] The process of regeneration in mammals is mainly compensatory growth or hyperplasia because while the lost mass of the liver is replaced, it does not regain its original shape.[6] During compensatory hyperplasia, the remaining liver tissue becomes larger so that the organ can continue to function. In lower species such as fish, the liver can regain both its original size and mass.[7]
