Main Results:

  • Amphibians and teleost fish exhibit significant heart regeneration.
  • Specific signaling pathways (e.g., Wnt, FGF) are crucial.
  • Key transcription factors and enhancers regulate the regenerative process.

Conclusions:

  • Non-mammalian cardiac regeneration provides a model for human heart repair.
  • Targeting identified pathways and factors may promote cardiac regeneration in mammals.
  • Further research can translate these findings into heart failure therapies.
