Auxilium Biotechnologies, a clinical-stage biotechnology firm, has bioprinted kidney and liver tissue aboard the Worldwide House Station (ISS), marking the primary time both tissue sort has been manufactured in orbit. The tissues, together with cartilage and 28 nerve restore implants, have been produced utilizing the corporate’s AMP-1 bioprinting platform throughout Mission AXLM-3, which launched on SpaceX-34 and splashed down off the California coast on June 17, 2026.
In response to Auxilium, the mission marks the primary time three distinct tissue sorts have been manufactured throughout a single spaceflight, and the primary time a single manufacturing platform has produced each residing tissue and implantable medical units on the identical flight. The kidney and liver tissues have been made utilizing cells and tissue designs from the Wake Forest Institute for Regenerative Medication (WFIRM), with Auxilium supplying the orbital manufacturing {hardware}.
Isac Lazarovits, Vice President of Engineering at Auxilium, mentioned producing a number of tissue sorts alongside dozens of implants in a single mission marks a step towards “routine manufacturing operations in orbit.”
Why Kidney and Liver Tissue Is More durable to Print in Orbit
Kidney and liver current a special problem than the vascular tubes, nerve implants, and knee meniscus tissue that orbital bioprinting missions have produced earlier than. WFIRM has been testing that problem instantly: in August 2025, the institute despatched 3D printed liver tissue to the ISS to review how microgravity impacts the expansion, stability, and performance of bioprinted organ constructs, constructing on its earlier work in NASA’s Vascular Tissue Problem, the place the staff’s vascularized tissue functioned for as much as 30 days in lab situations.
In house, zero gravity adjustments how cells distribute, behave, and cling inside vascularized tissue constructs, eradicating the exterior forces that trigger smooth tissue to break down beneath its personal weight on Earth. That’s a part of why house situations permit bioprinted constructs to tackle extra advanced geometries, together with voids, cavities, and tunnels much like the interior channel constructions kidney and liver tissue require.
Dr. Anthony Atala, MD, Professor and Director of WFIRM, mentioned the uniform cell distribution achieved aboard the station “factors to actual potentialities for manufacturing medical units and tissues in house.”
Organoid Analysis and Future Plans
The corporate factors to organoid manufacturing as a possible future software. Organoids are 3D tissue fashions utilized by researchers to review illness and display screen medicine; they’re at present manufactured on Earth and shipped to orbit to be used in experiments. The U.S. Meals & Drug Administration (FDA) has listed organoids amongst its New Method Methodologies initiative geared toward lowering reliance on animal testing, whereas the Nationwide Institutes of Well being (NIH) has expanded funding for comparable non-animal analysis platforms.
Constructing Towards Scalable Orbital Biomanufacturing
The kidney and liver tissue mission suits into Auxilium’s broader push to maneuver past single product demonstrations towards a producing platform able to producing a number of tissue and system sorts in a single flight.
Auxilium is working with Huge House and Starlab House on future orbital manufacturing platforms as industrial house stations put together to interchange the growing older ISS, and says it’s also growing capabilities meant to help future lunar and deep-space missions. Its collaboration with Starlab House particularly will deliver in orbit bioprinting and biofabrication to Starlab’s future industrial station, with the AMP-1 platform having beforehand produced perfusable vascular methods in microgravity.
The AMP-1 platform has been constructing towards this scale for a while. In an earlier ISS deployment, the system 3D printed eight medical units in simply two hours, a run CEO Jacob Koffler referred to as a landmark for house biomanufacturing on the time.
This mission expanded that output to twenty-eight implants alongside kidney, liver, and cartilage tissue. The mission concerned help from BioServe House Applied sciences, House Tango, and NASA‘s InSPA program, together with the astronauts aboard the ISS.
