Some amphibians are capable of limb regeneration as a result of their ability to produce blastemas after their time in the embryonic stage.

When a limb is severed from the body of an amphibian, all the epidermal cells in the severed area migrate to cover the open flesh.

After accumulating over the wound for several days, undifferentiated cells called fibroblasts starts duplicating the original cells and organs of the severed limb.

The original information of the disembodied limb's genetic coding is also found in the amphibians blastemas.

Making these rare cells is the most crucial part the the regeneration process.

Although the salamander is the only amphibian capable of regenerating throughout its entire lifespan, all amphibians can regenerate for a small amount of time out of their embryonic form.
