Tissue Regeneration in Animals
This tutorial describes how animals differ in their abilities to heal wounds and regenerate lost body parts or damaged tissues.
All animals can heal, and most can also regenerate some of their tissues and body parts. Regenerative capabilities among animals vary from the limited wound-healing abilities of humans to the remarkable capacity of some worms to reform their entire bodies from small clumps of cells. This Click & Learn presents some examples of regenerative abilities, and discusses the cellular and molecular mechanisms underlying them.
