Many animals are capable of regenerating complex body parts and restoring them to full functioning. Salamanders and planarians regrow damaged or missing body parts, while flatworms can replicate their entire bodies from minuscule components of themselves. The human body is comparatively limited in its ability to regenerate, as humans are only capable of renewing damaged organs such as the liver and skin. However, recent research in animal regeneration has revealed various stem cell strategies for regenerating body parts, that could one day be applied to humans.
