Our Science

Rejuvenation is pioneering advanced technologies to rewind cellular mechanisms of aging, including therapeutic telomere extension.

Understanding Telomeres

Telomeres are protective DNA sequences at the ends of chromosomes that shorten with each cell division. When telomeres become critically short, cells stop dividing or die. Since cell division is essential for human life, short telomeres drive aging and disease by preventing stem cells from dividing to repair and regenerate damage from daily wear-and-tear, injury, and disease.

Short telomeres are now recognized as a fundamental cause of aging-related diseases, including pulmonary fibrosis, liver disease, and bone marrow failure.

Our breakthrough technology can safely lengthen telomeres in specific cells, potentially reversing cellular aging and preventing or treating diseases and conditions caused by short telomeres.

The Role of Telomeres in Disease

Pulmonary Fibrosis

Short telomeres are the most common cause of familial pulmonary fibrosis and contribute to sporadic cases. Our therapy aims to restore telomere length in lung cells.

Liver Disease

Telomere shortening in liver cells leads to cirrhosis and increased cancer risk. We’re developing treatments to maintain healthy liver cell function.

Bone Marrow Failure

Short telomeres can cause bone marrow failure and blood disorders. Our approach could help maintain healthy blood cell production.

Our Therapeutic Approach

Telomerase Activation

We use modified mRNA to temporarily activate telomerase, the enzyme that naturally extends telomeres, in specific cells.

Targeted Delivery

Our proprietary lipid nanoparticle technology ensures the treatment reaches the right cells while minimizing off-target effects.

Controlled Treatment

The temporary nature of our approach allows precise control over telomere extension, maintaining safety and efficacy.

Monitoring & Analysis

Advanced telomere length analysis and biomarker tracking ensure optimal treatment outcomes.

Key Advantages

Safety First

Temporary activation avoids the cancer risks associated with permanent telomerase activation.

Precision Targeting

Our delivery system ensures the treatment reaches specific tissues and cell types.

Proven Science

Based on decades of research and validated through rigorous preclinical studies.

Clinical Trials

Rejuvenation’s clinical trial strategy targets unmet medical need via accelerated regulatory pathways, and broader trials to prevent or delay age-related disease in the general population.
