HyWnt3 promoter reproduces the endogenous expression. (A and B) Expression of HyWnt3 mRNA (A) and HyWnt3FL-EGFP transgene (B) in the adult Hydra. HyWnt3FL-EGFP is activated exclusively in the HyWnt3-expressing cells in the apical tips of the adult hypostome (arrow) and developing buds (arrowheads). (C and D) Induction of HyWnt3 and HyWnt3FL-EGFP in head-regenerating animals at 3 h after head removal, visualized by in situ hybridization for HyWnt3 (C) and EGFP (D). (E) Ectopic activation of HyWnt3FL-EGFP reporter in the body column at 48 h after alsterpaullone treatment for 24 h. (Scale bars: 100 μm.)
