Biotechnologies of Longevity: Reprogramming Cellular Time through Regenerative and Gene-Based Interventions

This article argues that emerging longevity biotechnologies converge on a unified, higher-order objective: the reprogramming of cellular time. Moving beyond a damage-centric view, I propose a framework in which strategies like partial cellular reprogramming, gene-based therapies, senolytic clearance, and directed regeneration are understood not merely as repair mechanisms, but as active tools to reshape the temporal state of cells. By restoring lost biological information and functional coordination, these interventions aim to reset, slow, or redirect the trajectory of aging. This perspective redefines longevity science from a pursuit of lifespan extension to a discipline of temporal engineering, providing a conceptual bridge between mechanistic aging biology and applied biotechnology.
