From: Q&A: What is regeneration, and why look to planarians for answers?
Functional perturbation of gene function by RNA-mediated genetic interference (RNAi) in planarians. (a) First RNAi effects reported in planarians show the specific loss of myosin (green) and tubulin (red) in regenerating tissues [23]. (b) Formation of multiple heads in an unamputated organism treated with β-catenin(RNAi) [25].
