What is it in a sea-star (or starfish for those who don't know the difference) that allows them to regrow an arm and the central disc isn't what I'm looking for what is it in there genes or cells that allow them to do this?

Presumably there are omnipotent stem cells in various parts of the sea star which can divide and differentiate into the various cell types necessary to regenerate a whole organism.
