How Space Research Helps Fight Infection and Aging Back on Earth

When an unmanned NASA spacecraft landed in Fort Lauderdale, Florida, a few days before Christmas 2023, its payload included liver cells from UC San Francisco that had spent two months orbiting Earth on the International Space Station. Physician-researcher Sonja Schrepfer, MD, PhD, sent the cells to the station for astronauts to conduct experiments on. Now, she was eager for their return to her UCSF lab so she could continue her research on how to reverse disease and encourage the human body to regenerate more quickly.
