Detailed explanation-1: -The liver is the only organ in the human body that can regenerate. Although some patients who have a diseased portion of their liver removed are unable to regrow the tissue and end up needing a transplant. Researchers from Michigan State University believe blood clotting factor fibrinogen may be responsible.

Detailed explanation-2: -The liver has a unique capacity among organs to regenerate itself after damage. A liver can regrow to a normal size even after up to 90% of it has been removed. But the liver isn’t invincible. Many diseases and exposures can harm it beyond the point of repair.

Detailed explanation-3: -After a wound or other damage, all the cells in the liver change and divide until the normal size of the liver is restored. This interesting process is commonly known as “liver regeneration.” If the injury to the liver is so serious that the liver cannot regenerate, a person may need a new liver, that is, a transplant.

Detailed explanation-4: -However, in chronic liver injury, it has been believed that liver progenitor cells (LPCs) or oval cells contribute to liver regeneration. Fundamentally, LPCs are defined as bi-potential cells similar to fetal hepatoblast, which can differentiate to both hepatocytes and BECs [1].

Detailed explanation-5: -Liver is the largest gland in the human body. It has the capacity of regeneration. In case of injuries, the cells of liver regenerate rapidly and compensate for the loss of cells due to the injury.
