Turritopsis dohrnii, the "immortal jellyfish," can revert from an adult back to its juvenile polyp stage, effectively restarting its life cycle. Scientists are investigating whether this remarkable ability holds clues for human aging research.
Biological Immortality
When stressed, injured, or simply old, this jellyfish can transform its cells, reversing differentiation and returning to an earlier developmental stage. It can theoretically do this indefinitely, making it biologically immortal.
Relevance to Human Aging
The cellular reprogramming involved is similar in principle to what scientists use to create stem cells. By understanding how the jellyfish achieves this naturally, researchers hope to develop therapies that could rejuvenate human tissues.
Recent genomic studies have identified genes unique to immortal jellyfish that may facilitate their remarkable transformations. These genes are now being studied in laboratory settings.
