Regeneration, the ability to regrow missing body parts after self-induced or traumatic amputation, has fascinated scientists for a long time.

The Regeneration of the Starfish. This is followed by the second, re-development phase that is a recapitulation of the events that occurred during limb development in the embryo. Regeneration: Can you imagine having the ability to regrow a part of your body? Community Regeneration is looking to recruit other Micro-Facilitators who will be provided with training and support to be able to lead the regeneration of their community. Starfish (or sea stars) are beautiful marine animals found in a variety of colors, shapes, and sizes.

Regeneration in humans is the regrowth of lost tissues or organs in response to injury. To eat two-shelled animals, the star pulls the shells pulls apart with its arms, inserts its stomach into the opening and digests. The nervous system also appears to be required for arm regeneration in Echinoderms because removal of the radial nerve in the starfish prevents arm regeneration . In planarians, the nervous system is required for proper regeneration of the gonads and accessory reproductive organs. Early attempts to control the population of sea stars involved chopping the sea stars into pieces. If an arm is damaged by a predator such as another starfish or a crab, the starfish can detach that arm and grow a new, healthy one. See more. Starfish’s Role Starfish is working with Bob Neville to identify ways for Community Regneration to grow and realise its full potential. 1), consisting of an early phase that begins with wound healing and ends with the formation of a regeneration blastema. Most species of starfish can regenerate, or regrow, damaged or lost arms.
All starfish resemble stars, and though the most common have only five arms, some of these animals can grow up to 40 arms. Salamanders accomplish this feat by dedifferentiation and respecification.

The most well-known species of sea stars, the crown-of-thorns starfish, decimated large populations of corals in the Great Barrier Reef. ... Starfish also eat spiny sea urchins, sponges, anemones, clams and oysters. The amazing sea creatures—part of a group of animals known as echinoderms—travel using their tube feet. One of the most amazing attributes of the starfish is their ability to re-grow a limb if lost in battle. Starfish have amazing power of regeneration.

Now while it may be impossible for humans to re-grow an appendage, the meanings associated with regeneration are quite appealing.
Cell regeneration is a biological feature of all living organisms from bacteria to plants and amphibians to mammals. This is in contrast to wound healing, or partial regeneration, which involves closing up the injury site with some gradation of scar tissue. Successful limb regeneration in a salamander is a two-step process (Fig. Formation of the apical ectodermal cap and regeneration blastema. Regeneration definition, act of regenerating; state of being regenerated. The process of regeneration may take as long as a year. They can also shed arms as a means of defense.
