Redwire BioFabrication Facility 3D prints a human knee Meniscus in space

It may be too soon to call it a trend but in-space bioprinting is something that raises researchers’ interest a lot. Last week, we were introducing the AstroCardia project. Today, we learn that Redwire Corporation, an expert in space infrastructure has 3D bioprinted a human knee meniscus on orbit. Described as a first of its kind, the fabrication held on the International Space Station (ISS), required the use of Redwire’s upgraded 3D BioFabrication Facility (BFF). This milestone opens the door to improved treatments for meniscal injuries, one of the most common injuries for U.S. Service Members.

This is a groundbreaking milestone with significant implications for human health,” said Redwire Executive Vice President John Vellinger. “Demonstrating the ability to successfully print complex tissue such as this meniscus is a major leap forward toward the development of a repeatable microgravity manufacturing process for reliable bioprinting at scale.”

The print returned to Earth onboard the SpaceX Crew-6 Mission for analysis following successful print operations in July.  Before returning to Earth, the print was cultured for 14 days on the ISS in Redwire’s Advanced Space Experiment Processor (ADSEP). The print was conducted as part of the BFF-Meniscus-2 Investigation with the Uniformed Services University of the Health Sciences Center for Biotechnology (4D Bio3), a biomedical research center that explores and adapts promising biotechnologies for warfighter benefit. The investigation was conducted by NASA astronauts Frank Rubio, Warren “Woody” Hoburg, and Stephen Bowen, and UAE astronaut Sultan Al Neyadi.

BFF is part of Redwire’s growing portfolio of technologies and innovative on-orbit capabilities enabling human spaceflight missions and commercial microgravity research and development in low-Earth orbit (LEO). Redwire has developed 20 research facilities for the ISS with 10 currently operating on station to deliver world-leading research. In July, Redwire announced plans to open a 30,000 square foot, state-of-the-art microgravity payload development facility with a mission operations center at the Novaparke Innovation & Technology Campus in Floyd County, Indiana, as the company looks to increase production of critical technologies enabling human spaceflight missions and commercial microgravity research and development in LEO.

On the upcoming SpaceX CRS-29 resupply mission to the ISS in November, Redwire will be launching microgravity research payloads focused on pharmaceutical drug development and regenerative medicine, including an experiment in bioprinting cardiac tissue.
