Abstract:
Regenerative potential is expressed to a maximum extent in echinoderms. It is a common
phenomenon in all the classes, extensively employed to reconstruct external appendages and internal
organs often subjected to amputation, self-induced or traumatic, rapidly followed by complete
successful re-growth of the lost parts. Regeneration has been studied in adult individuals as well as in
larvae. In armed echinoderms, regeneration of arms is obviously frequent: in many cases, the
detached body fragments can undergo phenomena of partial or total regeneration independently of the
donor animal, and, in a few cases (asteroids), the individual autotomised arms can even regenerate to
produce new complete adults, offering superb examples of cloning strategies. In the species examined
so far most results throw light on aspects related to wound healing, growth, morphogenesis and
differentiation, even though in most cases many crucial questions remain unanswered. The present
paper provides an overview of the current understanding of the phenomenon and covers the main
biological aspects of regeneration giving an idea of the “state of the art” across the phylum in terms of
experimental approaches and representative models.
