[In vivo and in vitro study of the effect of somatostatin and somatostatin-immunoreactive substance on the histology of the mantle edge in adult and juvenile snails (Helix aspersa)].
We have demonstrated structural differences between the mantle edge gland of young, adult and adult shell repairing snails. In vivo and in vitro, somatostatin-14 and somatostatin-immunoreactive substance (SSI) induce a juvenile status of the gland in adults and an activation of juvenile ones. These results suggest that they could regulate the growth and the repair of the shell and that the mantle edge gland might be considered as one of their tissue targets.
