Abstract
Age reprogramming and cellular rejuvenation therapies are revolutionizing the approach to aging and age-related diseases. These ground-breaking interventions target fundamental biological processes, including genomic instability, telomere attrition, and mitochondrial dysfunction, to restore cellular function and delay the onset of degenerative conditions. Emerging strategies such as epigenetic reprogramming, gene editing, stem cell therapy, and senolytic drugs show immense promise in extending health spans and potentially reversing aspects of aging. Despite marked progress in preclinical studies and early-stage clinical trials, translating these therapies into practical healthcare solutions presents significant challenges. Key issues include ensuring safety, optimizing delivery mechanisms, overcoming regulatory barriers, and addressing high costs. Moreover, ethical and economic considerations, such as equitable access and societal impacts, must be carefully addressed to prevent widening health disparities. The present review examines the current state of cellular rejuvenation research, highlighting both scientific advancements and the complex challenges associated with these therapies. With interdisciplinary collaboration, robust ethical frameworks, and scalable technological innovations, these therapies have the potential to transform healthcare. By shifting the focus from disease management to proactive health preservation, they offer a future where aging becomes a manageable and equitable process.
