Stem cells grown in microgravity aboard the International Space Station (ISS) have unique qualities that could one day help accelerate new biotherapies and heal complex disease, two Mayo Clinic researchers say.

Stem cells grown in microgravity aboard the International Space Station (ISS) have unique qualities that could one day help accelerate new biotherapies and heal complex disease, researchers say. The research analysis finds microgravity can strengthen the regenerative potential of cells. Microgravity is weightlessness or near-zero gravity.
