Immortal Jellyfish (Turritopsis dohrnii) - Fotografia de stock

Turritopsis dohrnii, commonly known as the "immortal jellyfish," is a species of jellyfish that has a unique ability to revert its cells back to their earliest form, essentially reversing the aging process. This extraordinary biological trait allows the jellyfish to potentially live indefinitely, leading to its nickname. When facing unfavorable conditions or stress, the adult Turritopsis dohrnii can transform its adult cells into specialized cells called "youth cells," effectively reverting back to its juvenile stage. This process, known as transdifferentiation, enables the jellyfish to restart its life cycle and avoid the natural aging process seen in other organisms. The remarkable regenerative abilities of Turritopsis dohrnii make it a subject of scientific interest, as researchers seek to understand and potentially harness these mechanisms for applications in regenerative medicine and anti-aging studies.
