Redwire Space has successfully bioprinted a human knee meniscus aboard the International Space Station (ISS), using its BioFabrication Facility (BFF). The meniscus was printed with living human cells and underwent a culture process on the ISS before being sent back to Earth.
The BFF-Meniscus-2 investigation involved printing a meniscus with living human cells, culturing it in space for 14 days, and then sending it back to Earth for further analysis. The goal was to demonstrate the ability to bioprint complex tissue in microgravity and develop a repeatable manufacturing process for bioprinting at scale.
Redwire Space aims to advance biotechnology and microgravity research in space. The company plans to launch payloads focused on pharmaceutical drug development and bioprinting cardiac tissue on a future mission to the ISS. Redwire also aims to integrate its biotech and in-space manufacturing technology into Sierra Space's Large Integrated Flexible Environment (LIFE) space station module.
