Scientists are shooting stem cells into space, hoping to make discoveries that help people on Earth. Some aim to overcome the difficulty of mass producing the cells on Earth that could be useful in future treatments for various diseases. Others explore how space travel impacts the body on a cellular level. And some help scientists better understand diseases such as cancer. Experiments by researchers at Cedars-Sinai Medical Center in Los Angeles and the University of California, San Diego, just arrived at the International Space Station. There have been earlier projects from the U.S., China and Italy.
High-flying experiment: Do stem cells grow better in space?
