The majority of regeneration-associated transcription factors fall within four transcription factor families. Select transcription factor-encoding transcripts from the helix-loop-helix (green), leucine zipper (purple), C2H2 zinc finger (red), and homeodomain families (blue) transcription factor families grouped according to their peak expression (schematically represented by grey curves). Although transcription factors from each of the families are represented at different stages in regeneration, leucine zipper transcription factors appear more prominent early in regeneration and homeodomain transcription factors are most prevalent later in regeneration.
