Biomanufacturing in low Earth orbit for regenerative medicine

Arun Sharma et al. Stem Cell Reports. .

Abstract

Research in low Earth orbit (LEO) has become more accessible. The 2020 Biomanufacturing in Space Symposium reviewed space-based regenerative medicine research and discussed leveraging LEO to advance biomanufacturing for regenerative medicine applications. The symposium identified areas where financial investments could stimulate advancements overcoming technical barriers. Opportunities in disease modeling, stem-cell-derived products, and biofabrication were highlighted. The symposium will initiate a roadmap to a sustainable market for regenerative medicine biomanufacturing in space. This perspective summarizes the 2020 Biomanufacturing in Space Symposium, highlights key biomanufacturing opportunities in LEO, and lays the framework for a roadmap to regenerative medicine biomanufacturing in space.

Keywords: biofabrication; microgravity; microphysiological systems; organoids; stem cells.

Biomanufacturing in low Earth orbit market subsegmentation revenue projection The LEO biomanufacturing market is broken into five primary subsegments: (1) cell and tissue tools and diagnostics, (2) cell and tissue therapy, (3) bioprinting, (4) cell therapy biomanufacturing, and (5) organoids. Projections are for the next 15 years.
