Introduction
For centuries, humanity has searched for ways to slow aging, extend health, and preserve vitality. Ancient civilizations sought mythical fountains of youth. Modern science searches for molecular pathways hidden inside living cells. Today, one of the most ambitious scientific ideas has entered a new phase: testing whether human cells can be biologically rejuvenated. A clinical trial has begun to evaluate a method known as cellular reprogramming—an experimental approach that attempts to restore aged cells to a younger functional state. Although this does not mean immortality or age reversal in humans, it represents one of the most significant milestones in longevity research.
