Scientists in 2025 uncovered a gene allowing what type of snail to regenerate an amputated eye in just one month?

In 2025, scientists made a fascinating discovery regarding the regenerative capabilities of the golden apple snail, or Pomacea canaliculata. These freshwater snails possess the extraordinary ability to completely regrow an amputated eye in approximately one month. This remarkable feat was detailed in research published in Nature Communications, highlighting the snail's unique biological mechanisms.

What makes this finding particularly significant is the surprising similarity between the golden apple snail's eye and the human eye. Both are "camera-type" eyes, featuring a lens, cornea, and retina. Researchers, including Alice Accorsi, found that many of the same genes responsible for human eye development are also present and active in the snail. Through gene-editing techniques like CRISPR-Cas9, they confirmed that a gene called pax6, crucial for eye formation in humans and other vertebrates, is also essential for the apple snail to develop its eyes.

This groundbreaking research establishes the golden apple snail as an invaluable model organism for studying complex organ regeneration. By understanding the genetic and molecular pathways that allow these snails to rebuild their eyes from scratch, scientists hope to uncover secrets that could eventually lead to new therapies. The long-term goal is to apply this knowledge to address human eye injuries and degenerative conditions like macular degeneration, offering a beacon of hope for restoring vision.
