Which human organ has the greatest regenerative capacity?
The liver has the greatest well-known regenerative capacity among major human organs. It can regrow after significant loss of tissue, sometimes after surgical removal of part of it.
Why do starfish have the ability to regrow arms?
Many starfish can regenerate lost arms because their tissues contain cells that can rebuild body parts. In some species, a single detached arm can even regenerate an entire body if part of the central disc remains attached.
Where are stem cells located in the human body?
Stem cells are found in several places, including bone marrow, skin, and the lining of the intestine. Different tissues contain stem cells for repair and renewal.
Whose work first showed that sea stars can regenerate lost arms?
Regeneration in sea stars was documented by naturalists and later experimental biologists over the 19th and 20th centuries. Some species can regrow arms, and in certain cases parts of the body can regenerate extensively.
