title: Somatostatin-like peptide and regeneration capacities in planarians.
abstract: The presence of a neuropeptide immunologically related to somatostatin (SRIF) has been investigated in the neurosecretory cells of two regenerating planarian species (Dugesia lugubris and Dendrocoelum lacteum). A correlation has been shown between the discharge of the SRIF-like-immunoreactive cells during the first hours after amputation and the capacity to regenerate, and between the persistence of numerous positive cells and the lack of regeneration. These results suggest that somatostatin might play a regulatory (inhibitory) role on the cellular proliferation which leads to the blastema edification.
