PRECISION GERMINATION™

The molecules that feed stem cell therapies.

Stem cells are grown in a medium of proteins and nutrients before they ever reach a patient. We are building those molecules in soybeans — plant based and scaled by U.S. farming.

Every stem cell therapy starts as cells that need to be fed.

What goes into the medium shapes what comes out: how well the cells grow, how closely one batch matches the next, and whether supply can keep pace as therapies move from trials to patients. Those ingredients should come from a source that is defined and free of diseases from animal sources.

From gene to cell

Gene

Seed

A soybean seed: nature’s bioreactor.

Protein

A molecule that feeds stem cells nutrients.

WHY SEEDS

A seed is already a protein factory.

A soybean seed spends a season storing protein and nutrients, then mobilizes all of it when it germinates. That is the window where we build the needed proteins.

​

Soybeans are grown on farmland around the world. Capacity comes from planting acres, not from building expensive bioreactors.

WHY IT MATTERS

Living medicines need consistent food.

Stem cell therapies are living medicines. Each dose begins as a small amount of cells that need to divide and expand in culture until there are enough to treat a patient. The medium they grow in is essential.

​

Ingredients taken from animals vary from lot to lot, depend on animal supply chains and carry disease risk. Therapies that must be made the same way, dose after dose, are better served by molecules that are animal-free and are produced in our controlled indoor environment.

​

​That is what we are building.
