Abstract:
:Whole-body regeneration relies on the re-establishment of body axes for patterning of new tissue. Wnt signaling is required to correctly regenerate tissues along the primary axis in many animals. However, the causal mechanisms that first launch Wnt signaling during regeneration are poorly characterized. We use the acoel worm Hofstenia miamia to identify processes that initiate Wnt signaling during posterior regeneration and find that the ligand wnt-3 is upregulated early in posterior-facing wounds. Functional studies reveal that wnt-3 is required to regenerate posterior tissues. wnt-3 is expressed in stem cells, it is needed for their proliferation, and its function is stem cell dependent. Chromatin accessibility data reveal that wnt-3 activation requires input from the general wound response. In addition, the expression of a different Wnt ligand, wnt-1, before amputation is required for wound-induced activation of wnt-3. Our study establishes a gene regulatory network for initiating Wnt signaling in posterior tissues in a bilaterian.
