Regeneration means the re-growth of part of the affected or lost organs of the remaining tissue. Animals can regenerate some organs, such as the liver. If a part of the liver is lost due to

**Figure 1.** The amphibian renewal preceding amphibian growth may offer hints to humans. After amputation, the wound heals to form the skin layer, and the underlying tissue undergoes a matrix reshaping, and cells in the region secrete soluble factors. The heterogeneous cell mass, blastema, is formed by the proliferation and migration of cells from neighboring tissues. Next, the blastema leads to the appearance of different new tissues that are spatially plastered to

illness or injury, the liver grows back to its original size, but not in its original form.
