Here's a simplified overview of the regeneration process:

1. Damage detection: The organism recognizes the damage or injury, triggering a response.
2. Cell activation: Specialized cells, such as stem cells or progenitor cells, are activated to participate in the regeneration process.
3. Cell proliferation: Activated cells multiply and differentiate into the required cell types.
4. Tissue formation: New cells organize into tissue structures, guided by signaling pathways and growth factors.
5. Pattern formation: The new tissue takes shape, following a predetermined pattern or blueprint.
6. Maturation: The regenerated tissue matures and integrates with surrounding tissues.
7. Functional recovery: The regenerated tissue or organ restores its original function.

Regeneration can occur through various mechanisms, including:

- Epimorphic regeneration (e.g., salamanders, zebrafish): Involves the formation of a blastema, a mass of undifferentiated cells that differentiate into new tissue.
- Morphallaxis
