wntP-1 is expressed at both anterior- and posterior-facing wounds during regeneration. (A–E) wntP-1 in situ hybridizations in intact animals (A) and regenerating head (B), trunk (C and D), and tail fragments (E) at time points (h) after surgery. Brackets, magnified regions at posterior- (B and D) or anterior- (C and E) facing wounds. (F–J) Diagrams depict surgeries. In situ hybridizations with wntP-1 riboprobe at time points after tissue slice (F), hole puncture (G), tissue triangle removal and tail amputation (H), oblique amputation (I), and lateral amputation (J). Anterior, top (A) or left (B–J). (A–E) Dorsal view (A and D, 48 h; B–D, 72 h); other panels, ventral view. (F–J) D, dorsal view; V, ventral view; arrows, regeneration-specific wntP-1 expression. (Scale bars: B–E, 100; A, F–J, 200 μm.) Panels represent ≥4 of 5 animals probed.
