Anterior and posterior planarian tips act as organizers, and cWnt signaling must be inhibited anteriorly and activated posteriorly to drive regeneration-linked stem cell proliferation.
- Why it matters: Organizers coordinate growth and differentiation, but how canonical Wnt signaling regulates these processes during whole-body regeneration in planarians is not well understood.
- What they did: The study grafted anterior or posterior tips to induce patterned head or tail formation, then tested cWnt roles using Notum and Wnt1, plus beta-catenin-1 and apc silencing in sublethally irradiated animals.
- The result: cWnt inhibition anteriorly and activation posteriorly are required for stem cell proliferation, and posterior wound cWnt signaling is necessary for differentiation of neurons, muscle, and parenchymal cells.
