Summary:Immunocytochemical investigation of the eyestalks of the larval and postlarval stages of the crayfish Astacus letodactylus, using an anti-Astacus-CHH serum, shows that immunopositive staining starts in the immediate posthatching larval stage, in neurosecretory cells of the medulla terminalis ganglionic X-organ (MTGX), in an MTGX-sinus gland tract, and in part of the axon terminals of the sinus gland. The number of these immunopositive cells increases during postlarval development. Neurosecretory granules belonging to distinct axon terminals of the neurohemal region show immunostaining. The mean diameter of the stained granules increases during postlarval development. The hemolymph glucose concentration in adult crayfish increases after injection of larval eyestalks.
