il1b overexpression induces aberrant apoptosis.

(A) A schematic diagram of the construct used; in this construct, the zebrafish heat shock protein 70l promoter drives the expression of mCherry and il1b harboring a signal sequence. (B) mCherry fluorescence in Tg(hsp70l:il1b) at 4 hr after heat shock. WT, sibling WT. Scale bar, 250 μm. (C) TUNEL analysis in the amputated fin fold of Tg(hsp70l:il1b) at 2 dpa. The diagram depicts the experimental procedure. HS, heat shock. Scale bar, 100 μm. (D) Quantification of TUNEL staining in (C). (E) Fin fold regeneration in Tg(hsp70l:il1b) and sibling WT larvae. Dotted lines indicate amputation planes and fin fold outlines. Scale bar, 100 μm. (F) Quantification of the length of the regenerate (length posterior to the amputation plane; shown in (E)). In (D) and (F), data are presented as means ± SEM. Student’s t test, ***p<0.001.
