Detailed explanation-1: -Some studies have suggested that stem cells can produce new liver cells. Others have implicated normal liver cells, called hepatocytes. The liver is composed of repeating structures called lobules. Each lobule consists of three zones.

Detailed explanation-2: -The parenchymal cells of the most solid glandular organs such as liver and kidney are stable cells. They are capable of undergoing rapid division upon injury to the organ to replace the dead cells.

Detailed explanation-3: -However, in terms of its regenerative capacity, the pancreas is not similar to the liver. Although acinar and endocrine cells increase their division rate after injury83, 84, 85, tissue mass is not fully restored86, 87, 88, 89, 90, 91, 92.

Detailed explanation-4: -There are two extensively studied mechanisms of liver regeneration: compensatory hyperplasia of hepatocytes and stem/progenitor cell-mediated regeneration.
