Conserved molecular programs support regeneration across multiple tissue types.

Select annotated genes with differential expression during early regeneration were grouped according to their primary in vivo function. Upregulation for at least one time point in the designated tissue is indicated by ▴ (≥2-fold), ▴ (≥5-fold), and ▴ (≥10-fold). Downregulation for at least one time point in the designated tissue is indicated by ▾ (≥2-fold), ▾ (≥5-fold), and ▾(≥10-fold). Up- and down-ward arrowheads in a given tissue column for the same gene indicate changes in expression direction over the investigated time course.
