Centenarian Longevity Biologics

Cells from people who lived to 100, to help others reach 100.

We harness the biology of centenarians — nature's only proven longevity phenotype — and manufacture their MSC-derived exosomes at scale via proprietary microgravity technology.

The Science

Why centenarians are the answer

Centenarians possess MSCs with superior DNA repair, enhanced proteostasis, and optimised metabolism — cells that have proven their resilience over 100+ years of biological stress. Their immune systems demonstrate compressed morbidity, avoiding the chronic inflammation that drives age-related disease in the rest of us.

The Dowrey et al. iPSC bank (Aging Cell, 2025) established the first longevity-specific stem cell repository from centenarian donors and their offspring. We ran proteomics across 3,977 proteins and applied ESM-2 transformer embeddings to identify 33 proteins consistently elevated in people who lived past 100.

Critically, 79% of these proteins are absent from the organ aging clocks identified across three major cohorts (Wang et al., Nature Aging 2025) — indicating an underexplored axis of longevity biology. These are our exosome cargo targets.

How centenarian cargo converges on apoptosis

Our working model: centenarian MSC-derived exosomes deliver elevated cargo proteins into a tumour cell, where independent signalling arms — metabolic (ADIPOQ → AMPK/mTOR), redox (SOD3), growth-factor (IGFBP2 → PI3K–AKT), and lipid (PTGDS → PPARγ) — converge on mitochondrial priming and caspase-3/7 apoptosis, with growth arrest as a secondary outcome. Network analysis across all 3,977 proteins, using ESM-2 embeddings, maps these routes before any lead advances.

The Clinostat · proprietary microgravity expansion
Part of a novel bioreactor system

MSC expansion accounts for approximately 96% of batch time in co-production models — the single most impactful manufacturing cost lever. The Clinostat — part of a novel bioreactor system — is an Arduino-controlled, variable-speed unit that creates microgravity conditions to lift MSC yield and enrich exosome cargo quality at the same time.

The Platform

Manufacturing advantage built in from day one

Cell expansion is the bottleneck in every MSC/exosome co-production pipeline. Most programmes don't own this layer. We do.

The Clinostat creates conditions to both increase MSC yield and — we hypothesise — enrich the secretome quality. First wet-lab experiments are running now at BioPunk / Frontier Tower, San Francisco, generating the first proprietary data on the microgravity–secretome relationship.

Centenarian MSC sourcing is in active negotiation with a leading academic centenarian-study biobank.

Unique Position

Three axes no competitor combines

01

Centenarian biology

Access to iPSC lines reprogrammed from centenarian donors (Dowrey et al., Aging Cell 2025) — cells that have proven their resilience over 100+ years, with superior DNA repair, enhanced proteostasis, and optimised metabolism.

02

Microgravity enhancement

Proprietary culture protocols on the Clinostat — part of a novel bioreactor system — our Arduino-controlled, variable-speed unit. MSC expansion accounts for ~96% of batch time; owning this layer is the primary manufacturing cost lever.

03

ESM-2 safety validation

Protein-protein interaction network analysis across 3,977 proteins using ESM-2 transformer embeddings. Mechanism-of-action elucidation and pre-clinical risk assessment before any lead advances.
