Regeneration of lost walking legs in the fiddler crab Uca pugilator is divided into three distinct phase-wound healing, basal growth, and proecdysial growth. By means of HPLC/RIA analysis of levels and composition of endogenous ecdysteroid hormones and in vitro assays of 14C-leucine incorporation, we have determined that the transition between anecdysis and proecdysis is the point at which lib bud growth is most effected by ecdysteroids. The growth that occurs during proecdysis is programmed during the anecdysis/proecdysis transition by a small peak of ecdysteroids (Peak I). Early exposure to 20-hydroxyecdysone at this critical window is necessary for further proecydsial growth of limb buds. The alter peak of edysteroids (Peak II) seen in the hemolymph of these crabs during late proecysis does not seem to be involved in the regeneration process.
