Regeneration is the natural process of replacing or restoring damaged or missing cells, tissues, organs, and even entire body parts to full function in plants and animals.

Regeneration is a remarkable biological process that enables organisms to repair or replace damaged or lost body parts, allowing them to survive and continue to function despite injury or disease. This process can occur in a variety of organisms, from simple single-celled organisms to complex animals such as salamanders, starfish, and certain types of lizards.

Regeneration can occur in different ways, depending on the organism and the type of tissue or organ involved. In some cases, regeneration occurs through the proliferation of undifferentiated cells, which can then differentiate into various cell types to rebuild the missing tissue or organ. In other cases, regeneration involves the reprogramming of specialized cells to become pluripotent and capable of differentiating into multiple cell types.
