Can the liver grow back if damaged?
The liver is a unique organ. It is the only organ in the body that is able to regenerate. With most organs, such as the heart, the damaged tissue is replaced with scar, like on the skin. The liver, however, is able to replace damaged tissue with new cells.
Is the liver the only organ that can regenerate itself?
Although some patients who have a diseased portion of their liver removed are unable to regrow the tissue and end up needing a transplant.
How does the liver regenerate?
However, if the liver is physical damaged (for example, a wound) or chemically damaged (by drugs or alcohol), its cells are pushed to divide and grow. This phenomenon is known as liver regeneration and it is even mentioned in Greek mythology.
How does liver regenerate itself after resection?
The dominant processes leading to regeneration of the liver following removal of tissue (partial hepatectomy) are compensatory hypertrophy (enlargement of hepatocytes) followed by hyperplasia (proliferation of hepatocytes).
Can liver regenerate itself after cirrhosis?
Fact: The liver is a highly regenerative organ but only if it’s still healthy enough to do so and doesn’t have extensive scar tissue. Once cirrhosis is present, your liver’s regeneration becomes very limited. That’s why in most cases, cirrhosis can’t be reversed.
