il11ra.L is widely and constitutively expressed in the intact tadpole and regenerating tail. (A) In situ hybridization of il11ra.L on a section of intact tadpole (upper) with an antisense probe, and (lower) with a sense probe. Anterior is left and dorsal is up. Scale bars: 500 µm. n = 4. (B–D) In situ hybridization of il11ra.L in a section of a regenerating tail. Anterior is left and dorsal is up. Arrowheads indicate notable signals. Scale bars: 500 µm. High magnification images of boxed areas in (C) and (D) are shown below. Scale bars: 100 µm. 1 dpa, n = 5; 3 dpa, n = 4; 5 dpa, n = 5.
