Stem cells destined to be grown into tiny, simplified, spherical versions of the human brain will soon be launched to the International Space Station (ISS).
In preparation for their journey to space, the cells were derived from adult human skin cells, according to a statement from the ISS National Lab, a U.S. government-funded national laboratory. The resulting stem cells are known as "induced pluripotent stem cells," which, under the influence of various chemical cues, can be made to transform into any type of cell in the body.
