A Lizard’s Regenerating Tail
Don’t ya hate it when that happens? You feel so short for a month.
Anoles are curious little lizards capable of ditching their tails when they feel threatened. This self-amputation, called autotomy, takes about 25 days for the tail to regrow. A paper published today in the open-access online journal PLOS ONE describes the genetic process anoles use to regenerate.
The researchers created the above graphic as a visual aid in their genetic sequencing. These ultra-thin slices of tail were taken from euthanized anoles at progressive stages of regeneration. This is very sad, but their sacrifices may someday help humans learn how to regenerate, too.
