Abstract

We have identified a novel planarian molecule, named TNEX59, that is regionally expressed. This molecule is localised mainly in the nuclei of mesenchymal cells in intact adult planarians in a distribution gradient, with the faintest signal located in the central body region, which includes the pharynx. The dynamics of localisation during regeneration depend on the regions to be regenerated. Our results suggest that TNEX59 is involved in the formation and/or maintenance of A/P planarian body pattern during regeneration.
