Key points from article :
Scientists are attempting to grow stem cells in to organs in the International Space Station.
On Earth stem cells tend to grow into single layered structures due to effect of gravity.
Goal is to use absence of gravity as a tool to support 3D growth of stem cells into tissue.
Astronauts on board the International Space Station are the ones conducting these experiments.
They are doing it inside a “mobile mini-laboratory” that was sent on a SpaceX rocket last week.
Will get the samples back and expect to see successful formation of ''organoids'' after a month.
