Who we are

Hardware and know-how to grow, process and study living cells in space

Our flagship platform, the Orbital Science Platform for Research & Innovation — OSPRI, is an automated, closed-system bioprocessing system for the International Space Station and commercial free-flyers.

OSPRI supports research and biomanufacturing with organoids, stem cells, cardiac tissue, extracellular vesicles and more. Founded in 2020 by a team with decades of spaceflight life-sciences experience, LEO Biosciences works with research and industry partners to turn microgravity into a practical setting for medicine and manufacturing.

Spaceflight, a unique environment

Unlocking bottlenecks in bioprocessing, and new market applications

Microgravity+Radiation=Novel cellular behavior
Enhanced 3D growthCells self-assemble into tissue-like structures without scaffolds or settling.
Altered proliferationGrowth rates shift in ways that can be studied and put to use.
Changes in viabilityCell survival responds to the orbital environment.
Changes in potencyFunction and output of cell products can change in orbit.
The OSPRI platform

A validated, microgravity-optimized platform for in-space cell biomanufacturing, engineered to scale

Proven terrestrial bioprocessing technology, re-engineered for microgravity. Multi-phase fluid flow, aeration and radiation shielding are designed in from the start.
